A trapezoid has two bases. They are the parallel sides.

directrix · Answer

Only one of the bases is shown in the option list. Do you see it?  @R5lover1997

This problem is asking us to assume that lines that look parallel are indeed parallel. That is an assumption that we normally cannot make in geometry.

BD

directrix · Answer

Not side BD. It is one of the two parallel sides. See attachment.

The diagram should have been marked as to which pair of sides is parallel. 

I took that liberty with the diagram.

The answer is one of the two sides marked with the blue arrows. Which one of those two sides is listed in the options?
