Answer 5

From the diagram can't even figure out which two sides are parallel in the trapezoid.

Answer 6

Sorry, It was the best I could do.

Answer 7

But can you tell which two sides are parallel? AB & CD or AD & BC?

Answer 8

Ab and Dc

Answer 9

Without doing lengthy calculations, my guess would be 4. Average of AB and CD because it connects midpoints (or half way).

Answer 11

But it is a guess. Hopefully a correct one.

Answer 12

Thank you none the less.

Answer 13

It is 4! You are welcome. You can close the question if it has been answered.
