An irregular hexagon.
A shape with parallel sides but no right angles is called a parallelogram
Such a shape is called a rhombus.
Rhombus
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.
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.
It is a square.
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.
This is a parallelogram called a rectangle. A square has four right angles and four sides that are equal in length.
A RECTANGLE has 4 sides and 4 right angles.
A shape with 11 sides and angles is called an 11-gon, or a hendecagon.
This Shape is a HEXAGON which has 6 sides and 6 angles.
