Back

Front

If ∠E is 45° and ∠B is 55°, what is the measure of ∠C in congruent triangles?

Back

∠C = 80°.

Front

What is the definition of congruent triangles?

Back

Triangles that have the same size and shape, meaning all corresponding sides and angles are equal.

Front

List one criterion for triangle congruence.

Back

Side-Angle-Side (SAS) congruence criterion.

Front

What is the Angle-Side-Angle (ASA) congruence criterion?

Back

If two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the triangles are congruent.

Front

What is the Side-Side-Side (SSS) congruence criterion?

Back

If all three sides of one triangle are equal to all three sides of another triangle, the triangles are congruent.

Front

How can you prove that two triangles are congruent using CPCTC?

Back

By showing that all corresponding parts (sides and angles) of the triangles are equal after establishing their congruence.

Front

What is the relationship between corresponding angles in congruent triangles?

Back

Corresponding angles in congruent triangles are equal.
