As defined, a quadrilateral. Could be others, but need to know about parallel and/or equal sides...
A kite :) /\ \/
A kite, arrowhead or irregular quadrilateral.
A kite An irregular quadrilateral can be made having only 1 right angle.
it is a right angled trapezium
A three sided shape is a triangle but the given angles are incorrect because a triangle can't possibly have a right angle and an obtuse angle because its 3 interior angles must add up to 180 degrees.
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.
Decagon is 10 sided figure. Internal angles of 10 sided figure is (2 x 10 - 4) right angles = 16 x 90 degrees, hence one angle is (16 x 90)/10 = 16 x 9 = 144 degrees
An irregular pentagon.
An irregular septagon: the right-angle will prevent it being regular.
A right angle triangle.
Such a figure is called a square. Actually only one right angle is enough to force the the other angles to be right, and if three sides are equal, that forces all sides in such a figure to be equal. Exercise: Prove that any 4-sided figure( called a quadrilateral in math books) with three equal sides and one right angle is a square.
A right scalene triangle.
