CPCTC

Front

What does CPCTC stand for?

Back

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

Front

What is the definition of congruent triangles?

Back

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

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 AB and side DE?

Back

Side AB is congruent to side DE.

Front

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

Back

If two angles of one triangle are equal to two angles of another triangle, the triangles are congruent.

Front

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

Back

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

Front

What is the purpose of CPCTC in solving triangle problems?

Back

CPCTC is used to prove that corresponding parts of congruent triangles are equal, which helps in solving for unknown angles or sides.

Front

Given ∆XYZ ≅ ∆ABC, if ∠X = 30° and ∠A = 30°, what can be concluded?

Back

∠X is congruent to ∠A.

Front

If ∆PQR ≅ ∆STU, and QR = 5 cm, what is the length of ST?

Back

ST = 5 cm.
