A rhombus.
A figure with four right angles is called a rectangle. A specific type of rectangle in which all the sides are of equal length is called a square.
A parallelogram is a figure with different lengths and widths(also called breadth) where opposite sides and opposite angles are equal. But the angles are not 900 each. In fact, no angle in a parallelogram is a right angle as presence of 1 right angle proves all the angles to be right angles. A parallelogram with 4 right angles is called as a ''rectangle''
A parallelogram can have four equal sides that will not meet at right angles. The term diamond can also be used in this context.
rhombus
A square.
A Rhombus
A figure with four equal sides and no right angles is a rhombus. A rhombus is comprised of two acute angles and two obtuse angles.
A four sided figure with four equal sides and no right angles is a diamond, or a rhombus. If it had four right angles, it would be a square.
A figure with four right angles is called a rectangle. A specific type of rectangle in which all the sides are of equal length is called a square.
a square
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.
Trapezoid
A square is a plane geometric figure having 4 equal sides and 4 right angles.
A parallelogram is a figure with different lengths and widths(also called breadth) where opposite sides and opposite angles are equal. But the angles are not 900 each. In fact, no angle in a parallelogram is a right angle as presence of 1 right angle proves all the angles to be right angles. A parallelogram with 4 right angles is called as a ''rectangle''
A parallelogram can have four equal sides that will not meet at right angles. The term diamond can also be used in this context.
