CPCTC Congruent Triangles

Front

What does CPCTC stand for in the context of congruent triangles?

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

The corresponding angles of congruent triangles are equal.

Front

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

Back

AB ≅ DE.

Front

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

Back

The ASA criterion states that 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 Side-Angle-Side (SAS) congruence criterion?

Back

The SAS criterion states that 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 Side-Side-Side (SSS) congruence criterion?

Back

The SSS criterion states that if all three sides of one triangle are equal to all three sides of another triangle, then the triangles are congruent.

Front

If ∆JKL ≅ ∆MNO, what can be said about ∠J?

Back

∠J ≅ ∠M.

Front

What is the relationship between corresponding sides of congruent triangles?

Back

The corresponding sides of congruent triangles are equal in length.

Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, meaning all corresponding sides and angles are equal.

Front

If ∆RST ≅ ∆UVW, what can be concluded about the sides RS and UV?

Back

RS ≅ UV.
