问题 In parallelogram WXYZ shown above, WY is perpendicular to YZ and the measure of angle WZY is 72°. What is the measure of angle XYW?

选项 A、12°
B、18°
C、36°
D、58°
E、72°

答案B

解析 The correct answer is B. According to the figure, angle WZY is 72°. Note that angle WYZ is 90°, which means that angle ZWY must be 18°(180°- 72°-90°= 18°). Therefore, the angle in question must also be 18°.
