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
