  1. 10-4 Inscribed AnglesN# 4 4/9/2014 SLG : Students will be able to find measures of inscribed angles and inscribed polygons.

  2. D Inscribed angles are equal to half of the arc they intercept. C B E B If two inscribed angles of a circle intercept the same arc, then they are congruent. D C E If an inscribed angle equals 90 degrees, then the arc that it intercepts will be a semicircle, and its endpoints are the endpoints of the diameter. D B D C E B D If a quadrilateral is inscribed in a circle, then its opposite angles are supplementary. C F
