CPCTC

Front

What does CPCTC stand for?

Back

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

Front

If ΔABC ≅ ΔXYZ, what can we say about the angles?

Back

The corresponding angles of the triangles are congruent, meaning ∠A ≅ ∠X, ∠B ≅ ∠Y, and ∠C ≅ ∠Z.

Front

If two triangles are congruent, what can we say about their corresponding sides?

Back

The corresponding sides of the triangles are equal in length.

Front

What is the significance of CPCTC in triangle congruence?

Back

CPCTC allows us to conclude that if two triangles are congruent, then all their corresponding parts (sides and angles) are also congruent.

Front

If ΔABC ≅ ΔXYZ, what is true about side AB and side XY?

Back

AB ≅ XY.

Front

What is the relationship between ∠B and ∠Y if ΔABC ≅ ΔXYZ?

Back

∠B ≅ ∠Y.

Front

If the measure of ∠C is 100º in ΔABC, what is the measure of ∠Z in ΔXYZ if ΔABC ≅ ΔXYZ?

Back

∠Z is also 100º.

Front

What can we conclude about the sides AC and XC if ΔABC ≅ ΔXYZ?

Back

AC ≅ XC.

Front

If two triangles are congruent, how many pairs of corresponding angles are congruent?

Back

Three pairs of corresponding angles are congruent.

Front

If ΔABC ≅ ΔXYZ, what can we say about the side lengths?

Back

All corresponding side lengths are equal.
