a quadrangle with only one right angle
Such a quadrangle cannot exist. The right angle must be formed by one of the parallel sides and one of the non-parallel sides. Then the angle formed at the other end of that non-parallel side would also be a right angle (the non-parallel side would be a transversal intercepting the two parallels). But then the quadrangle has two right angles, and not just one. No its Trapezoid

OK, got it! What's the next step ?
A rhombus
a quadrangle with only one right angle
how do you draw a quadrangle that has at least 1 right angle.
I'm guessing a right-angled quadrangle.
If the question is about only one right angle, then the answer is a kite, arrowhead or a miscellaneous quadrangle which has no specific name.

Draw a square / rectangle, a quadrangle is just a shape with 4 sides, as long as one is a right angle your golden

Two possibilities are a kite, or an irregular quadrilateral with one right angle!
It can be a trapezium, kite, arrowhead, or a general quadrangle. Squares and rectangles also have one right angle - they have more that 1, but that still means they have 1.
