An irregular hexagon.
A shape with parallel sides but no right angles is called a parallelogram
A shape with 8 sides is called an octagon. If it has 4 right angles, it can be classified as a right octagon, which is a specific type of octagon where some angles are right angles. However, a regular octagon does not have right angles; thus, a shape with 8 sides and exactly 4 right angles may be an irregular octagon. An example could be a shape resembling a rectangle extended into an octagonal form.
Such a shape is called a rhombus.
Rhombus
A shape with five sides would be a pentagon, but a shape can not have 5 right angles. Squares and Rectangles are both shapes with 4 sides and 4 right angles. They are the only shape with the same amount of right angles as there is sides.
A shape with four unequal sides is called an irregular quadrilateral.
A shape with no right angles but is still a quadrilateral is called a rhombus. A rhombus has four sides of equal length and opposite sides that are parallel to each other. Although its angles are not right angles, they are all congruent.
It is a square.
This is a parallelogram called a rectangle. A square has four right angles and four sides that are equal in length.
A 2D shape with four straight sides and no right angles is called a rhombus. In a rhombus, all four sides are of equal length, but the angles are oblique, meaning they are either acute or obtuse. Another example of such a shape is a trapezoid that does not have any right angles. Both shapes are classified as quadrilaterals.
A RECTANGLE has 4 sides and 4 right angles.
A figure with four sides, two of which are parallel and with no right angles, is called a trapezoid (or trapezium in some countries). In this shape, the parallel sides are known as the bases, while the other two sides are called the legs. The angles between the legs and the bases can vary, which is why there are no right angles in this configuration.
