Question

Is it possible for opposite angles in a trapezoid to be congruent? 
Sometimes?
Always?
Never?

anonymous · Answer

I'd say never, or else it would be a square.

anonymous · Answer

Do you know which property states that? I'm pretty confused on all of this

anonymous · Answer

I could be wrong though.

anonymous · Answer

Sometimes.
A parallelogram is a particular kind of trapezoid, which has opposite angles congruent.
(So is the square)

anonymous · Answer

A trapezoid is not a parallelogram.

mertsj · Answer

A parallelogram is NOT a trapezoid.  A trapezoid, by definition, is a quadrilateral with EXACTLY one pair of parallel sides.  Therefore, a parallelogram which, by definition, has two pair of parallel sides is NOT a special trapezoid!!!

anonymous · Answer

Therefore the previous answer is incorrect.

anonymous · Answer

Think about it, even if it's an irregular trapezoid, they wouldn't be congruent. Draw them out, it helps.
