a triangle
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.
a right triangle
A four-sided shape with one right angle is a quadrilateral. There is no more specific term, unless it has more than one right angle or has equal sides.
It fits the description of a right angle triangle
There is no name for such a figure. Quadrilaterals such as a trapezium or kite or even one with no equal sides can have a right angle.

Five side is always a pentagon, but there's no pentagon that always has exactly one right angle. A regular pentagon has no right angles. An irregular pentagon can have one, two, or three right angles, or none.

A shape that has three sides and includes right angles is a right triangle. In a right triangle, one of the angles is exactly 90 degrees, and the other two angles are acute. The sides of the triangle consist of the two legs that form the right angle and the hypotenuse opposite the right angle.
A shape with five sides, one right angle, and one obtuse angle is known as a pentagon. Specifically, it can be an irregular pentagon, where the right angle is 90 degrees and the obtuse angle is greater than 90 degrees but less than 180 degrees. The remaining angles can be acute or right angles, as long as the total sum of the interior angles equals 540 degrees.
What about the other angle(s). You need at least 3 sides and 3 angles to make a closed figure.
Draw a square / rectangle, a quadrangle is just a shape with 4 sides, as long as one is a right angle your golden
