Mike constructed a quadrilateral POQS. He used a compass and straightedge to accurately construct line segment OS, as shown in the figure below. Which could be the measures of angle POS and angle POQ? 
 (A)m POS = 30°mZPOQ = 50°
 (B)mZPOS - 30°,mZPOQ-65°
 (C)m POS -25°,mZPOO-65° (D)mZPOS=25mZPOQ -50°
