This video gives more detail about the mathematical principles presented in SAS Triangle Congruence.
This video shows how to work step-by-step through one or more of the examples in SAS Triangle Congruence.
Defines congruent triangles and states the ways to prove two triangles are congruent.
Provides practice problems to determine if two triangles are congruent.
Provides a two column proof that two triangles are congruent.
Nine question quiz. Students must examine diagrams of triangles and the coordinates of triangles and determine if they are congruent using the SAS congruency theorem. Students must justify their reasoning. Students must also draw (on the coordinate plan) an example and non-example of triangles that can be proven congruent using the SAS theorem and then explain their reasoning.
