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.
A right trapezoid (or right trapezium) has one pair of parallel sides and one right angle. In this shape, one of the non-parallel sides is perpendicular to the two parallel sides, forming a right angle. This configuration allows for various applications in geometry and design.
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
None. Triangles do not have parallel sides

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.
