Find the measure of and if in Fig 3.34.


(If you find is there more than one method to find ?)

According to the figure,

P + Q = 180° (Angles on the same side of transversal)


P + 130° = 180°


P = 50°


R + S = 180° (Angles on the same side of transversal)


90° + R = 180°


S = 90°


Yes, there is one more method to find the measure of m P, m R and m Q are given. After finding m S, the angle sum property of a quadrilateral can be applied to find m P
