Question

ABCD is a trapezium in which ab is parallel to dc and Angle A is equal to angle b is equal to 45 degree find angle d

Answer 1

ABCD is a trapezium in which AB and CD are parallel and <A = <B = 45. What is <C and <D?

Since <A = <B, the figure is an isosceles trapezium. So <A +<D = 180 or <D = 180–45 = 135 deg. Again <B +<C = 180 or <C = 180–45 = 135 deg.

Hence <C = <D = 135 deg.

hope this helps you out!
