$\angle b$ and $\angle d$ are alternate angles, hence are same

$\angle b$ and $\angle a$ are vertical angles , hence are same

Again, $\angle a$ and $\angle d$ are corresponding angles, hence are same

So the answer is A because A,B are equal to each other and D is a corner angle which is the same as A. –  Little Jon Feb 15 '13 at 19:13
