|dw:1417206632439:dw| in an isosceles triangle you have the parallel sides that you call bases.  Base angles share a base.

So... if |dw:1417207013274:dw| Made a typo on the labeling.

In an isosceles trapezoid, the "legs" of the trapezoid are the non parallel sides, so if those are congruent, or equal, then

$\angle A =\angle D$  and $\angle B = \angle C$

jhannybean · Answer

So again, if $\angle A$ and $\angle D$ are base angles, meaning they share he same base (parallel side), as well as $\angle C $ and $\angle B$  base angles, then these will always form congruent angles.
