Lesson 10-4: Inscribed Angles Geometry CP Mrs. Mongold -Inscribed angle: an angle inside the circle with sides that are chords and a vertex on the edge of the circle Inscribed angle = ½ intercepted arc -An inscribed right angle, always intercepts a semicircle -If two or more inscribed angles intercept the same arc, they are congruent A Ex: Angle CAE = ½ arc CE X C E A Inscribed angle BAC intercepts a semicircle- so angle BAC =90 B C Inscribed angles GDF and GEF both intercept arc GF, so the angles are congruent D F E G Find the measure of angle X Find the measures of angles 1, 2, 3, and 4 Find the measure of angle R Find the measure of angle I Find the measure of angle B Find the measure of angle D Find angle S and T
