Question from Gautham: In trapezoid ABCD, sides AB and CD are parallel, angle A = 2angle D, and angle C = 3angle B. Find angle A. |
Hi,
I drew a diagram of your trapezoid and extended $BA$ to a point $P.$
Since $AB$ and $DC$ are parallel what is the relationship between the interior angle at $D$ and the angle $PAD?$
