the diagnol of a rectangle PQRS meet at point O.if anglePOQ=124.find angleOSR

As angle POQ is 124 degree
Hence SOR is vertically opposite angle so it is 124
In triangle SOR , side SO = OR (diagonals of a rectangle are equal and bisect each other)
So the angle OSR = angle ORS
And sum of angle of triangle = 180
Hence 124 + OSR + ORS = 180
So 2OSR = 180- 124
OSR = 56/2 = 28
