State if the two triangles are congruent: Triangle ABC and Triangle DEF with sides AB = DE, AC = DF, and angle A = angle D.

Back

Yes, they are congruent by SSS.

Front

State if the two triangles are congruent: Triangle XYZ and Triangle PQR with angle X = angle P, side XY = side PQ, and angle Y = angle Q.

Back

Yes, they are congruent by ASA.

Front

What is the definition of congruent triangles?

Back

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

Front

What is the SAS postulate?

Back

If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.

Front

What is the ASA postulate?

Back

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

Front

What is the AAS postulate?

Back

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