You can have two right angles and still be only a trapezoid. With three right angles then it would be a rectangle.
A right angle triangle has no parallel sides
Parallel sides do not intersect. Perpendicular sides intersect at a right angle.
no triangles have parraell sides!
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
Yes, a trapezium (or trapezoid in American English) can have one right angle. In such a trapezium, one pair of opposite sides is parallel, and the right angle can occur between one of the non-parallel sides and one of the parallel sides. This configuration is common in various geometric applications and can have unique properties based on the angles and lengths of the sides.
None. Triangles do not have parallel sides
a right angle triangle.

that's a rhombus with no right angle
No, right triangles do not.

rhombus
In plane geometry, a shape with four sides, two of which are parallel and have the same length, cannot have a reflex angle.
A right angle trapezoid has 2 right angles, an acute angle and an obtuse angle It has a pair of opposite parallel sides of different lengths The 4 interior angles add up to 360 degrees
