Rahim is constructing a proof to show that the opposite angles of a quadrilateral inscribed in a circle are supplementary. Which step would be the
second step in his proof, given the following information?
Given: Quadrilateral QRST is inscribed in circle X.
Prove: 2Q is supplementary to S.
1. MORS + STO- 360, because there are 360° in a circle.
2
because of the division property of equality.
