In plane geometry, a shape with four sides, two of which are parallel and have the same length, cannot have a reflex angle.
An irregular pentagon.
The shape you are describing is a trapezoid. A trapezoid is a quadrilateral with at least one pair of parallel sides. It can have two right angles, but it does not have any lines of symmetry due to its asymmetrical nature.
A right angle triangle has no parallel sides
A right triangle has three sides and one right angle.

a trapezoid
A rhombus, (or a square if there's a right angle).
i think its a PARALLELOGRAM
its a rhombus
a right triangle, a pentagon w/ a right angle, alot of shapes with right angles.
It could be a right angle triangle
It fits the description of a right angle triangle
It is an irregular quadrilateral. It cannot have any parallel sides.
