HW- 11.4 Practice B 11.3 to 11.5 Quiz TUESDAY 4-29-14 www.westex.org HS, Teacher Website Name _________________________ Geometry CPA 11.4 Inscribed Angles GOAL: I will be able to: 1. Find the measure of an inscribed angle. 2. Use inscribed angles and their properties to solve problems. Date ________ An ____________ __________ is an angle whose vertex is on a circle and whose sides contain chords of the circle. An _______________ ______ consists of endpoints that lie on the sides of an inscribed angle and all the points of the circle between them. A chord or arc subtends an angle if its endpoints lie on the sides of the angle. Example 1: Finding Measures of Arcs and Inscribed Angles Find each measure. A. mPRU B. YOU TRY: Find each measure. A.
