After doing these investigations, your students will have a great grasp of the triangle and how the concept can be used in many different circumstances. Review one of the proofs of the Pythagorean Theorem that uses squares constructed on each side of a right triangle. Use a man’s shadow to determine how far he is from the base of a tree. Dig for buried treasure based on information on a treasure map. These investigations are geared toward the middle school student, but could easily be adapted or used as is in a review of geometric figures for older students.
