Front

Name the postulate that makes triangles congruent if two sides and the included angle are known.

Back

SAS (Side-Angle-Side) Postulate

Front

Name the postulate that makes triangles congruent if all three sides are known.

Back

SSS (Side-Side-Side) Postulate

Front

Name the postulate that makes triangles congruent if two angles and the included side are known.

Back

ASA (Angle-Side-Angle) Postulate

Front

Name the postulate that makes triangles congruent if two angles and a non-included side are known.

Back

AAS (Angle-Angle-Side) Postulate

Front

Name the postulate that makes right triangles congruent if the hypotenuse and one leg are known.

Back

HL (Hypotenuse-Leg) Postulate

Front

If two triangles have two sides of one triangle equal to two sides of another triangle, what additional information is needed to prove they are congruent?

Back

The included angle must be equal.

Front

What is the relationship between congruent triangles?

Back

They have the same shape and size.

Front

If triangle ABC is congruent to triangle DEF, what can be said about their corresponding parts?

Back

AB = DE, BC = EF, CA = FD and ∠A = ∠D, ∠B = ∠E, ∠C = ∠F.

Front

What is the significance of the ASA postulate in triangle congruence?

Back

It allows us to prove triangles are congruent by knowing two angles and the included side.
