This is a rectangle, or the special case of the square (all sides equal).
It is an isosceles triangle; and if it has a 90 degree angle and two 45 degree angles then it is an isosceles right angle triangle.
If each angle is 90 degrees the shape is called a square.
A rhombus
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.
the answer is square's.

its a rhombus
This is a rectangle, or the special case of the square (all sides equal).
A square is a regular shape. It will have four sides of equal length, and a right angle (90 degrees) in each corner.
It is an isosceles triangle; and if it has a 90 degree angle and two 45 degree angles then it is an isosceles right angle triangle.
A shape in which every line/edge is not the same length OR A shape in which every angle is not equal
If each angle is 90 degrees the shape is called a square.
