Materials Needed: paper, straight edge, compass, pencil, computer with internet access Students will…use instruction from textbook, teacher demonstration, and the website www.mathopenref.com to learn the appropriate construction techniques. The student will construct using a compass and staight-edge - a line segment congruent to a given line segment, the bisector of a line segment, a perpendicular to a given line from a point not on the line, a perpendicular to a given line at a point on the line, the bisector of a given angle, and an angle congruent to a given angle. Using
these basic constructions the student will construct a 45 degree angle, an isosceles right triangle, a square, and a rectangle.

Reflection on lesson: Students enjoy this activity. The student has a concrete
application that allows them to start viewing 3-dimensional objects when illustrated on 2dimensional paper. If more time were available, students could explore more with computer simulations of geometry - particularly Geometer's Sketchpad. Students could also explore Cross-Sectional Geometry (which occurs when a plane intersects a threedimensional object).
