CPCTC

Front

What does CPCTC stand for?

Back

Corresponding parts of congruent triangles are congruent.

Front

If two triangles are congruent, what can be said about their corresponding angles?

Back

The corresponding angles are congruent.

Front

If ∆ABC ≅ ∆DEF, what can be concluded about ∠A and ∠D?

Back

∠A ≅ ∠D.

Front

What is the significance of CPCTC in triangle congruence?

Back

It allows us to conclude that corresponding parts of congruent triangles are also congruent.

Front

How can you determine if two triangles are congruent?

Back

By using congruence criteria such as SSS, SAS, ASA, AAS, or HL.

Front

What is the SSS congruence criterion?

Back

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

Front

What is the SAS congruence criterion?

Back

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

Front

What is the 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 AAS congruence criterion?

Back

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

Front

What is the HL congruence criterion?

Back

If the hypotenuse and one leg of a right triangle are equal to the hypotenuse and one leg of another right triangle, the triangles are congruent.
