Triangle Congruence Theorems (Side-Angle-Side)

Triangle Congruence Theorems (Side-Angle-Side)

Author: Leif Park Jordan

    Present how if two sides and the included angle of one triangle are congruent to two sides and the included angle of a second triangle, then the two triangles are congruent.


    Review how to use the corresponding sides and corresponding angles of two congruent triangles to write a congruence statement (ex ΔABC ΔDEF).


    Provide examples that demonstrate how to prove two triangles congruent using the SAS triangle congruence theorem.


This packet should help a learner seeking to understand how to use the triangle congruence theorem (side-angle-side) to prove triangles congruent.
