Can't draw it on this site. Try this: Draw a one inch horizontal line. Below the beginning of that line and 1/4 inch to the right, draw a second one inch line at a slight downward diagonal. Now connect the ends of both lines, right to right and left to left. Not a math major, so I down't know the name of it, but that should be it.
Wikipedia defines a trapezium (trapezoid) as a quadrilateral with one pair of parallel sides. However, it also acknowledges that there is disagreement as to whether or not that means exactly one pair or at least one pair. Under the first definition a trapezium could not be a square whereas under the second, it would. Sorry not to give you an unambiguous answer but ...
There are two definitions for trapezoids. One defines them as a quadrilateral with at least two parallel lines, which would include parallelograms. The other strictly defines trapezoids as quadrilaterals with exactly two parallel lines.
A regular polygon has all its angles of equal measure, and its sides of equal length. In the case of a quadrilateral, that would mean a square. A concave quadrilateral must have at least one reflex angle and so cannot be a square. So it cannot be regular.
a square
any regular quadrilateral will have at least one pair, this includes, but is not limited to, square, rectangle and parallelogram
No. Even in the non-US use of the term (a quadrilateral with at least one set of parallel lines), the lengths of the parallel lines may not be the same, and/or the angles formed by each adjacent side may be different (as in a rhomboid), resulting in diagonals of extremely different lengths.Only in rectangles are diagonals "always" of equal length.
No. A quadrilateral is trapezoid if it has at least one pair of parallel sides.

They both have at least one pair of parallel sides and at least one pair of sides of equal length.
A quadrilateral with at least one pair of parallel sides has multiple possible names, depending on what type of quadrilateral it is.SquareRectangleParallelogramRhomboidTrapezoidYou are probably looking for only one pair of parallel sides, which is a trapezoid - both regular and irregular.
No. An example of a quadrilateral that doesn't have a pair of parallel sides is a kite.
A trapezoid, if my memory serves me correctly.
It is a trapezoid that has only 1 pair of parallel sides of different lengths

No. A trapezoid is defined as a quadrilateral with two parallel sides. Therefore, the quality of quadrilateral is necessary, and this condition is satisfied. ... Any other shape can have four sides, but if it does not have (at least) two parallel sides, it cannot be a trapezoid.
