9.5/9.6 Inscribed Angles and Quadrilaterals HW: 9.5 (#5 13) 9.6 (#9 13 ) Essential Question: How does the measure of an inscribed angle relate to a central angle? Angle formed by 2 chords with a common endpoint Measure of an inscribed is the measure of the intercepted arc 2 inscribed s w/ the same intercepted arc are Circle Formulas/Thms Packet Take 3min to write these thms in your packet in your own words.

Polygon inside a circle and whose vertices are on the circle inscribed oppositesupplementary Circle Formulas/Thms Packet Take 2min to write this thm in your packet in your own words. Write it so you will understand it. Add a picture too! Inscribed Quadrilateral Thm x + 80 = 180 x = z = 180 z = 87 y + 71 = 180 y = = 164 x = 164/2 x = y = 180 y = 98 105 + (7x +1) = 180 7x = 74 x You find y! (4y +14) + (7y +1) = y = 165 y = 15 You find x and y! x = 180 x = 72 y + 88 = 180 y = 92 Mid Chapter Exit Slip 1) Find the arc length AND area of the sector. Keep the pi. 3) Find RQ.
