Question

Abcd is a trapezium in which ab is parallel to cd and ad is equal to bc. D and f are two

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.
