Question

Prove that : The opposite angles formed by two intersecting lines are of equal measures. Given : Line PQ and RS intersect at point O such that P – O – Q and R – O – S To prove : (1) < POS = < ROQ (2) < SOQ = < POR Proof : (i) < POS + = = 1800 ………. (ii) < SOQ + = 1800 ………. (iii) < POS + = < SOQ + (iv) < POS = < ROQ Similarly we can prove that < SOQ = < POR​
