CPCTC

Front

What does CPCTC stand for?

Back

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

Front

If ∆ABC ≅ ∆XYZ, what can we conclude about the corresponding angles?

Back

∠A ≅ ∠X, ∠B ≅ ∠Y, ∠C ≅ ∠Z.

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.

Front

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

Back

The corresponding sides of congruent triangles are equal in length.

Front

What is the significance of the symbol '≅' in geometry?

Back

The symbol '≅' indicates that two figures are congruent.

Front

If ∆LMK ≅ ∆LMT, what can we say about the sides LM and LT?

Back

LM ≅ LT.

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

If ∆XYZ ≅ ∆KLM, what can we conclude about side XY?

Back

XY ≅ KL.

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

If ∠A ≅ ∠M, what can we infer about triangles that include these angles?

Back

The triangles may be congruent if the corresponding sides are also equal.
