Exercise 15 Page 504

Recall the theorem that states that if a quadrilateral is a parallelogram, then its opposite angles are congruent.

105

Let's find the measure of ∠ XYZ.

Notice that the angles that measure 105^(∘) and m∠ XYZ are opposite angles. Recall the following theorem.

If a quadrilateral is a parallelogram, then its opposite angles are congruent.

Therefore, the measures of these angles are equal. m∠ XYZ= 105
