the circle that is of an arc in degrees is the measure of the corresponding central angle. 1. Use the definitions above to fill in the blanks: In the figure below left, 110 ZAOB is 135 ZAPB is and AB is A 270 B O Section 1 Angles P с a Q A A. In the figure above right, which arc is intercepted by ZAOQ? Which arc is intercepted by ZAPQ? B. If La = 50°, what is Zc? Explain. In general, what is the relationship between Za and Zc? Explain. D. In the figure at the right, if ZAOB = 140° and Za = 50°, what is Zb? What is Zc? What is Zd? What is ZAPB? 6. Repeat Problem 5 with ZAOB = 140° and three different values for Za.
