That it has 4 sides and a pair of parallel sides of different lengths
To prove that a quadrilateral is a right trapezoid, you need to show that it has one pair of parallel sides and one pair of right angles. This can be done by using the properties of parallel lines and perpendicular lines.
It makes sense because it is true. There are other quadrilaterals whose diagonals are perpendicular.
To determine if a quadrilateral is a parallelogram, you need to show that either pairs of opposite sides are equal in length, or that pairs of opposite angles are equal, or that the diagonals bisect each other. Alternatively, if both pairs of opposite sides are parallel, it also confirms that the quadrilateral is a parallelogram. Any one of these conditions is sufficient to classify the quadrilateral as a parallelogram.

____________ / | /_____________ | Crappy drawing, I know, but a right trapezoid has two right angles(right side of picture), and two supplimentary non-right angles(left side of drawing). This is still a trapezoid because in order to be a trapezoid, there must be one and only one pair of parallel lines, and four sides. That's it, thus this is a possible trapezoid.

I don't think this is possible. there is not a quadrilateral with these qualities. If it is a quadrilateral, it will automatically have parallel lines, but there is not one that has both. The closest one would be the trapezoid, with a set of parallel lines, but no right angle. The square and rectangle have two sets of parallel lines and 4 right angles.

A square
just have 4 lines that join up... a quadrilateral is a 4 sided shape
polygon and rectangle
It is a quadrilateral based pyramid.
