Two opposite sides of a quadrilateral are the same length. The diagonals of the quadrilateral are also the same length. Prove the quadrilateral is a trapezoid.
(In reply to re: Solution

- the definition of trapezoid is the North American definition
- the quadrilateral is not a self-intersecting quadrilateral
