In the figure, PQRS is a trapezium in which PQ  SR. if P = 55o and Q = 70o, find R andS.

PQ  SR   P + S = 180o     (co-interior angles)

 55o + S = 180o
  S =180o – 55o = 125o
Now  Q + R = 180o                             (co-interior angles)
 70o + R = 180o 
  R = 180o – 70o = 110o
Hence R = 110o and S = 125o
