Exercise 81 Page 289

Consider the SSS (Side-Side-Side) Congruence Theorem.

See solution.

Practice makes perfect

Let's add the given information to the diagram.

Examining the diagram, we notice that QR is shared between △ PRQ and △ SQR. Therefore, by the Reflexive Property of Equality we can claim that this side is congruent as well.

With this information we have enough to prove congruence by the SSS (Side-Side-Side) Congruence Theorem. If we separate the triangles, we see that ∠ P and ∠ S are corresponding angles and therefore congruent.

Let's show this as a flowchart.
