Front

What does CPCTC stand for?

Back

CPCTC stands for 'Corresponding Parts of Congruent Triangles are Congruent.'

Front

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

Back

Their corresponding angles are equal.

Front

If ∆ABC ≅ ∆DEF, what can be concluded about side AB and side DE?

Back

AB ≅ DE.

Front

What is the relationship between corresponding sides of congruent triangles?

Back

The corresponding sides of congruent triangles are equal in length.

Front

If ∠A ≅ ∠D and ∠B ≅ ∠E, what can be inferred about triangles ABC and DEF?

Back

If two angles of one triangle are congruent to two angles of another triangle, the triangles are congruent (AA criterion).

Front

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

Back

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

Front

What is the Side-Angle-Side (SAS) criterion for triangle congruence?

Back

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

Front

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

Back

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

Front

If ∆XYZ ≅ ∆KLM, what can be said about ∠Y and ∠K?

Back

∠Y ≅ ∠K.

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning all corresponding sides and angles are equal.
