Just wanna make sure that I got this right: Quadrilateral BCDE is inscribed inside a circle as shown below. Write a proof showing that angles C and E are supplementary. My answer: In BCD: BCD + CBD + CDB = 180 degrees The inscribed angles are congruent so: CBD = CED CDB = CEB By Substitution: BCD + CED + CEB = 180 degrees By angle addition postulate : angle C + angle E = 180 degrees
