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 sides AB and XY?

Back

AB ≅ XY.

Front

What is the importance of the order of vertices in triangle congruence?

Back

The order of vertices indicates which angles and sides correspond to each other in congruent triangles.

Front

If ∆XYZ ≅ ∆KLM, what can we say about the angles ∠Y and ∠L?

Back

∠Y ≅ ∠L.

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

How do you denote that two triangles are congruent?

Back

You use the symbol '≅' to denote that two triangles are congruent.

Front

What is the significance of the congruence statement ∆FGH ≅ ∆VHW?

Back

It indicates that the corresponding sides and angles of triangles FGH and VHW are equal.

Front

If two triangles have two pairs of equal sides and the included angle is equal, what can be concluded?

Back

The triangles are congruent by the Side-Angle-Side (SAS) postulate.

Front

What is the Side-Side-Side (SSS) congruence criterion?

Back

If three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What does it mean if ∠C measures 100º in a triangle?

Back

It means that angle C is one of the angles in the triangle, and it contributes to the triangle's overall angle sum of 180º.
