Congruence Extended: A Setting for Activity in Geometry

- Summary

Abstract

One way to add relevance and interest to a geometry course is to provide opportunities for students to conjecture about possible theorems, to test these conjectures inductively, and then to prove the theorems where appropriate. The following is a brief outline of a unit on congruence of geometric figures for the secondary level (either junior high or high school).
