Quadrilateral. No other special name. A kite could have 1 right angle - that's possible, but there is no special name for a quadrilateral with only 1 right angle.
An irregular quadrilateral.
A right-angle triangle.

It fits the description of a trapezoid
The figure described is a quadrilateral known as a right-angled trapezoid. It has three right angles (90 degrees) and one angle that is less than a right angle (acute) and one angle that is greater than a right angle (obtuse). This configuration allows the sum of the angles to equal 360 degrees, satisfying the angle sum property of a quadrilateral.
The answer is a trapezoid.
