Question

please give me answer fast?? ​

Answer 1

Answer:

Given: AB and CD are two parallel chords of a circle.

If one side of a cyclic quadrilateral is produced then the exterior angle is equal to the interior opposite angle.

∴ ext. ∠DCE = ∠B and ext. ∠EDC = ∠A

A || B

∴ ∠EDC = ∠B and ∠DCE = ∠A

∴∠A = ∠B

Hence, ΔAEB is isosceles.
