Exercise 12 Page 291

Consider the Base Angles Theorem.

If RQ≅ RS then ∠RQS ≅ ∠RSQ.

Practice makes perfect

The statement RQ≅ RS tells us that these sides are congruent. Let's mark that in our diagram.

According to the Base Angles Theorem, if two sides of a triangle are congruent, then the angles opposite them are congruent.

Now we can copy and complete the statement. If RQ≅ RS then ∠RQS ≅ ∠RSQ.
