Playground Polygons are closed figures that have straight sides. triangles This triangle is made up by the two poles and the ground. Squares are quadrilaterals with four equal sides. A square also has to have 4 right angles. This playground picture of a 2 square board creates a square. A rectangle is a quadrilateral with two pairs of parallel lines. This playground picture is of a rectangle made by the bars. A rhombus is a quadrilateral with no right angles, but two pairs of parallel lines. This fence is creating a rhombus with the wires. What I learned so far in math is all basic geometry. We learned about polygons and angles and 3D shapes. I learned about 2D shapes also. We learned about quadrilaterals, the four sided polygon. We also learned a lot about Power Point and cameras and how to insert pictures. I really had fun so far, but now we’re getting ready for the test. I am sad that we can’t do more on polygons and everything else, but there’s everything else to learn in math.
