Geometry: Congruent Or Not?

by Texas Instruments

Overview

Students investigate whether AAA, SAS, or SSA relationship guarantee that two triangles are congruent or not.

Key Steps

Students will investigate whether AAA, SAS, or SSA relationships guarantee that two triangles are congruent or not.
Using the Cabri™ Jr. application, students will manipulate triangles that have a given relationship. They will try to make more than one triangle with the given side lengths and angle measures to show whether or not enough information is given to prove congruency.
