Question

In quadrilateral MNOP, angle M is congruent to angle N. Which parallelogram, trapezoid, or rhombus could quadrilateral MNOP be?

Answer 1

Since <M and <N are next to each other, both have to be equal to 90 degrees, but there's nothing else specified, so it could be a trapzoid, or a special case of a trapzoid, a parallelogram, or a special case of a parallelogram, a rhombus.

In your case.... D.
