Consider the following trapezoid.

A trapezoid is depicted with vertices labeled A, B, C, and D in a clockwise direction. The left and right legs of the trapezoid, AB and CD respectively, are marked with single hash marks, indicating they are of equal length. The top base, BC, is shorter than the bottom base, AD. The angle at vertex A is labeled as $54^\circ$54°. Angles at vertices A and D are lower base angles. Angles at vertices C and B are upper base angles.
a
