there is no unique name for a shape like that as it would just be called an irregular quadrilateral
A rectangle or a square: both have four sides and a right-angle of 90 degrees forming the four corners.
A square is a two-dimensional shape with four equal sides and four right angles.
This is a rectangle, or the special case of the square (all sides equal).
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.
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.
A rectangle or a square: both have four sides and a right-angle of 90 degrees forming the four corners.
In plane geometry, a shape with four sides, two of which are parallel and have the same length, cannot have a reflex angle.
A square is a two-dimensional shape with four equal sides and four right angles.
With right angles it is a square.Without right angles it is a rhombus.

a square!
The shape can only be a rectangle! A rectangle is a four-sided 2-dimentional figure, where every angle is a right angle, opposite sides are parallel, but the 4 sides are NOT equal.
A rectangle has four sides whereas a right angle triangle has only three sides.
parallelogram!
A Square and Rectangle are both a Quadrilaterals(A four sided shape)and have both have 4 Right Angles.In addition,a irregular Quadrilateral(A four sided shape of no sides of the same length)may have a right angle( A 90 degrees angle)but it depends on how you draw it on paper.Cretth 2010
