QUEST Geometry Scavenger Hunt Adrianne Gilford Linh Nguyen Jennifer Petru Point A point is a "dot" on a piece of paper. We identify this point with a number or letter. A point has no length or width, it just specifies an exact location. Nature Man-made One of the spots For this picture, one on the ladybug Textbook must connect the represents a A, B, C, and Q all points to reveal the point represent points picture. because it specifies an exact location. Parallel Lines Two lines in the same plane which never intersect are parallel lines. Man-made The cracks in are parallel Nature lines on this plane because they will never These trees intersect. Textbook represent parallel lines because they We say that two line segments are never intersect. parallel if the lines that they lie on are parallel. If line 1 is parallel to line 2, we write this as line 1 || line 2 Parallel Lines (cut by a perpendicular transversal) Parallel Lines: Lines in the same plane that do not intersect. Transversal: A line (or segment) that intersects two coplanar lines (or segments) at two distinct points. The diagram below shows the eight angles formed by the transversal and two segments. Man-Made Nature The fence is parallel and The leaves of the fern are is cut by a perpendicular parallel and they are cut Textbook transerval. by a perpendicular transversal which is the This model can be stem. used in textbooks to show parallel lines cut by a transversal. Parallel Lines cut by a non- perpendicular transversal Man Made Nature The bamboo in this The lines from the power bamboo forest form lines creates a non- parallel lines and perpendicular transversal. some bamboo form a non-perpendicular transversal across Text book others. A non-perpendicular line that cuts across parallel lines. Pythagorean Triple Pythagorean triple is a set of three positive whole numbers a, b, and c that are the lengths of the sides of a right triangle. This means that a, b, and c satisfy the equation from the Pythagorean Theorem, Man-made Nature The cracks in are parallel lines on this plane These trees because they will never represent parallel intersect. lines because they never intersect. Textbook The smallest example is a = 3, b = 4, and c = 5. You can check that 32 + 42 = 9 + 16 = 25 = 52. Fractal A fractal is a geometric shape which is self- similar and has fractional (fractal) dimension Man-made The patterns inside the Nature letter A are self-similar The leaf patterns of at every level and they the fern illustrate a are repeated. fractal because they are self-similar and repeated. Textbook The subdivisions of the triangle into smaller triangles represent self-similar and repeated patterns. Oval Having the figure of an egg; oblong and curvilinear, with one end broader than the other .

Man-made Nature These donuts are The wings of the congruent because butterfly are they are the same size congruent because and same shape. they are the same size and same shape. Textbook The two figures are the same size and same shape, so they are congruent. Ray A ray is a straight line that begins at a certain point and extends forever in one direction. The point where the ray begins is known as its endpoint. Man-made Nature The trees in this These trees start on painting symbolize rays the ground and because the endpoints extend up, so they start at the ground and are rays. extend upwards. Textbook The name of a ray with endpoint A and passing through a point B as "ray AB“. Pentagon A figure that has five sides. Man-made Nature There are five sides to The arms of the this sign, therefore, it is starfish create a a pentagon. pentagon . Textbook The figure above is a pentagon because it is a five sided polygon. Ellipse A squashed, stretched or otherwise distorted circle with both ends the same size. Man-made Nature The plate is an ellipse These grapes in that it is elongated represent ellipses and both ends are the because they look like same. stretched circles. Textbook The figure above is an ellipse because it is shaped like a stretched circle and both ends are the same. Prism A polyhedron with two congruent, parallel bases that are polygons, and all remaining faces parallelograms. Man-made Nature The cake is a The desert dunes rectangular prism represent a prism. Textbook because its bases are rectangles. The green figure is a pentagonal prism because the bases are pentagons. The aqua figure is a triangular prism because the bases are triangles. The yellow figure is a hexagonal prism because the bases are hexagons. Line Man Made Nature The line in the road is a This fault line shows an example man made line to keep of a line extending infinitely in cars on the road. both directions. Text Book A straight path that goes in two directions without end. Transversal Man Made Nature This bridge’s structure These blood vessels show shows many transversal transversal lines. lines. Text Book A line that cuts across a set of lines or the sides of a plane figure. Quadrilateral Nature Stone Henge’s rock Man Made formations are natural The black and white forms of quadrilaterals. square patterns in this picture are examples of quadrilaterals. Text Book A polygon with four sides and four vertices. Similar Items Nature Man Made The starfish and the star on the design on the shell The beach ball and both are similar with the baseball are similar in a star shape. circle shape. Text Book Items that have the same shape but not necessarily the same size. The leaf and small box are both similar with the heart shape . Cylinder Man Made Nature This fish tank is in a These redwood tree trunks cylinder shape. are cylinder shaped in nature. Text Book A 3-dimensional figure with one curved surface and two circular bases. Sphere Nature Man Made The structure at Epcot This flower’s bulb is a sphere shape. Center at Disney World forms a sphere shape. Text Book A 3-dimensional figure that is the set of all points that are a given distance from a fixed point. Intersecting Lines Man Made Nature This railroad crossing sign Intersecting lines in a green has intersecting lines. leaf. Text Book Lines that meet or cross at a common point. Angle Nature Man Made This tree’s branches show’s This bracket is made into many different angles. a right angle. Text Book A figure formed by two rays (sides) with the same endpoint (vertex). Chord Man Made Nature This no truck sign shows This bug’s shell show’s a a chord in the circle. chord separating the yellow from the pink shell. Text Book A line segment that connects two points on a circle. Tangent Nature Man Made These strawberries on This record player is an the vine are an example of a tangent example of tangent lent. lines. Text Book a line or plane which touches a given curve or solid at a single point. Plane A surface containing all the straight lines that connect any two points on it. Man-Made Nature The top of a table is considered a plane The land of the desert is portrayed as a plane. Textbook A flat surface that stretches into infinity. Triangle The plane figure formed by connecting three points not in a straight line by straight line segments; a three-sided polygon. Nature This is an example of a triangle in nature. The butterfly’s wing is in the Man-Made shape of a triangle. See it? This is a man-made triangle. It is a sign stating that there has been an accident. We see similar signs daily. Textbook This is a text book example of a triangle. It shows you that all sides are equal. Circle An ellipse in which the two axes are of equal length; a plane curve generated by one point moving at a constant distance from a fixed point. Nature Man-Made This is a man hole where This is an example of the liquid flows. It is man- moon. It is a perfect circle. made. It is a circle. It was There are no sides. Textbook found in my apartment complex. This is a circle that could be found in a textbook. It is very simple and shows the radius and the center, p. Cube A three-dimensional shape with six square or rectangular sides. Nature Ice cubes are from water. They are frozen. This is an Man-Made example of a cube. This is a picture of dice. They are in the shape of cubes. Textbook A cube has 6 sides. This can be seen in textbooks too. Square A plane rectangle with four equal sides and four right angles; a four-sided regular polygon. b Nature Gems are found in nature. This diamonds face is in the shape of a square. It is also pretty pink. c Man-Made a This blue plate is man- made. It is in the shape of a square. All sides are equal. d Textbook A square must be equal on all 4 sides. This is a square that could be found in a textbook. Cone A shape whose base is a circle and whose sides taper up to a point. Nature Shells can be in the shape of cones. This shell is brown and white and forms a cone. Man-Made This type of cone is seen all of the time. It can be used to help students cross the street. Textbook This cone could be seen in a textbook. It labels the height, the side and from the center to the side. Parabola A plane curve formed by the intersection of a right circular cone and a plane parallel to an element of the cone or by the locus of points equidistant from a fixed line and a fixed point not on the line. Nature Water fountains are great examples of parabolas. Here is one. Man-Made This necklace creates a parabola. Textbook Here is an example of a parabola. It shows the axis and the vertex, or the midpoint. Arc A continuous portion of a circle. Nature A rainbow is an arc. It is made from the son and the rain. It occurs naturally. Man-Made The Saint Louis Arch is a great example of a man-made arc. Textbook This is an example showing the distance of an arc. Pyramid A polyhedron having a polygonal base and triangular sides with a common vertex. Nature Pyramids are natural wonders. They are great Man-Made places to visit and great ways Pyramids can be man-made to gain information about the just like this food pyramid. It past. tells about what food should be eaten and how much. It Textbook is changed quite often. This pyramid can be found in textbooks. It gives the dimensions of a pyramid.
