ABCD is a trapezium in which AB∥CD and AD=BC show that I) ∠A=∠B

1.	ABCD is a trapezium in which AB∥CD and AD=BC show that I) ∠A=∠B II) ∠C=∠D III) triangle ABC congruent to triangle BAD IV) diagonal AC =diagonal BD
Answer» $A B C D$ is a trapezium in which $A B ∥ C D$ and $A D = B C$ show that I) $∠ A = ∠ B$ II) $∠ C = ∠ D$ III) triangle $A B C$ congruent to triangle $B A D$ IV) diagonal $A C$ =diagonal $B D$
