This lesson focuses on triangle congruence; it shows the ways to prove that triangles are congruent.

In this lesson on congruent triangles, students explore how to use postulates to identify if triangles are congruent by SSS, SAS, ASA, and AAS.

See how triangles are congruent where all corresponding angle pairs and sides are the same.

Given two triangles, determine whether they are congruent and use that to find missing angle measures. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
