Question

ABCD is a trapezium in which AB//CD.If AD=BC, show that angle A =angle B and angle C=angleD.

Answer 1

angle A = angle B (bcoz it's an isosceles trapezium)
even angle C =angle D
You can apply the same reason
ACCORDING TO TRAPEZIUM PROPERTY THE SUM OF ADJACENT ANGLES IN A TRAPEZIUM ARE EQUAL i.e., angle A=angle D
angle B=angle C
