A 4 sided polygon is called a quadrilateral. Depending on where the two right angles are, would put the quadrilateral into different subsets. For example if the two right angles are on adjacent corners (and the other 2 angles are not right angles), then it is a trapezoid. If the 2 right angles are in opposite corners, and the other 2 angles are not right angles then it would be a kite-shaped quadrilateral.
A shape with parallel sides but no right angles is called a parallelogram
Squares and rectangles have a two-dimensional shape with four sides and four right angles.
A right trapezoid.
A rectangular shape, or a rectangle.
Not possible ! If the shape has four right-angles, at least two sides must be the same length.
A rectangle has two right angles and parcel sides
A shape with parallel sides but no right angles is called a parallelogram
A rectangle has two sets of two equal sides and four right angles.
Squares and rectangles have a two-dimensional shape with four sides and four right angles.
its impossible to have two right angles in a four sided figure without having the other two sides be right angles too
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.
The shape that has only one set of parallel sides and two right angles is a trapezoid (or trapezium in some regions). In this case, it specifically refers to a right trapezoid, which has two right angles. The other two angles can be acute or obtuse, but the defining feature is the single pair of parallel sides.
