Exercise 3 Page 619

What can you say about the size and shape of two triangles that have three congruent corresponding sides?

The statement is true.
Explanation: See solution.

Practice makes perfect

Examining the diagram in the exercise, we see that the two triangles have three congruent corresponding sides: PQ≅SR, PT≅ST and QT≅RT This is enough information to claim congruence by the SSS Congruence Theorem.
