Question

Quadrilateral ABCD is inscribed in the circle. Which sentence is true?

A) A and B are supplementary
B) A and C are supplementary
C) m∠A = m∠B
D) m∠C = m∠D

Answer 1

The true statement on Quadrilateral ABCD is B) A and C are supplementary. The theory is that when a quadrilateral is inscribed in a circle, the value of opposite angles always adds up to 180 degrees. The summation of two angles resulting to 180 degrees is called supplementary angles.
