CPCTC

Front

What does CPCTC stand for?

Back

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

Front

What is the significance of the congruency statement ∆ABC ≅ ∆DEF?

Back

It indicates that all corresponding sides and angles of triangles ABC and DEF are equal.

Front

If ∆PQR ≅ ∆XYZ, what can we conclude about ∠P and ∠X?

Back

∠P ≅ ∠X.

Front

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

Back

Their corresponding sides are equal in length.

Front

What is the relationship between ∠A and ∠D if ∆GHI ≅ ∆JKL?

Back

∠A ≅ ∠D.

Front

If ∆MNO ≅ ∆PQR, what can we conclude about side MN and side PQ?

Back

MN ≅ PQ.

Front

What does it mean if two angles are congruent?

Back

It means they have the same measure.

Front

If ∆ABC ≅ ∆DEF, what can we say about the lengths of AB and DE?

Back

AB ≅ DE.

Front

What is the purpose of using CPCTC in geometry?

Back

To prove that corresponding parts of congruent triangles are equal.

Front

If ∠X ≅ ∠Y and ∠Y ≅ ∠Z, what can we conclude about ∠X and ∠Z?

Back

∠X ≅ ∠Z (Transitive Property of Congruence).
