CPCTC

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 we say about their corresponding angles?

Back

The corresponding angles of congruent triangles are equal.

Front

If ΔABC ≅ ΔXYZ, what can we conclude about side AB and side XY?

Back

AB = XY.

Front

What is the significance of the congruence statement in triangle congruence?

Back

The congruence statement indicates which corresponding parts of the triangles are equal.

Front

If ∆PIG ≅ ∆COW, what can we say about the corresponding sides?

Back

PI = CO, IG = OW, PG = CW.

Front

What is the first step in proving two triangles are congruent?

Back

Identify the corresponding parts of the triangles.

Front

What is the Side-Angle-Side (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 Angle-Side-Angle (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 Hypotenuse-Leg (HL) theorem?

Back

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

Front

If ΔABC ≅ ΔXYZ, what can we say about angle A and angle X?

Back

∠A ≅ ∠X.
