Question

What do you mean by corresponding parts of the congruent triangle (cpct)

Answer 1

Define corresponding parts of the congruent triangle:

Two triangles are said to be congruent when corresponding sides and corresponding angles of both triangles are equal.

Corresponding parts of the congruent triangle means when two or more triangles are congruent, then all of their corresponding angles and corresponding sides are congruent.

Example.

Two congruent triangles are shown below,

The corresponding parts of the congruent triangle are,

$$\begin{gathered} BC=QR \\ AC=PQ \\ AB=PR \\ \angle A=\angle P \\ \angle C=\angle Q \\ \angle B=\angle R \end{gathered}$$
