Could you me answer 13 and 14

13.) a quadrilateral has equal sides and angles measures of 80 degrees,100 degrees,80 degrees, and 100 degrees in what ways can that quadrilateral be classified? explain

It would have to be a rectangle because each second side of a is different so the line across from it is the same number and the length of the rectangle is always less unless you put it up so therefore it would have to be classified as a rectangle. It depends, since a trapezoid may have right angles but it doesn't necessary to have or they arnt required. A trapezoid only specifies that it must be a quadrilateral, or a closes four sided shape and that it only must have one pair of parallel sides.
