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 YZ?

Back

AB = YZ.

Front

What is the significance of the congruence symbol (≅) in geometry?

Back

The congruence symbol indicates that two figures have the same shape and size.

Front

If ∆LMK ≅ ∆LMT, what can we say about ∠K and ∠T?

Back

∠K ≅ ∠T.

Front

In congruent triangles, how are the sides related?

Back

The corresponding sides of congruent triangles are equal in length.

Front

What is the relationship between ∠C and ∠Z if ΔABC ≅ ΔXYZ?

Back

∠C ≅ ∠Z.

Front

If two triangles have two pairs of equal angles, what can we conclude about the triangles?

Back

The triangles are congruent by the Angle-Angle (AA) criterion.

Front

What is the measure of ∠C if ∠E is 45° and ∠B is 55° in congruent triangles?

Back

∠C = 80°.

Front

What does it mean for two triangles to be congruent?

Back

It means that they have the same size and shape, with corresponding sides and angles being equal.
