A rhombus is one of them
hexagon and octagon.
A shape with four equal straight sides is a square. In addition to having equal sides, a square also has four right angles. Another example of a shape with four equal sides is a rhombus, although its angles are not necessarily right angles. Both shapes are classified as quadrilaterals.
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 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 rectangle book has a rectangular shape, with four straight sides and four right angles.
A shape that has four straight sides and four angles is defined as a quadrilateral. If all four angles are right angles, it is a rectangle, and if all four sides are congruent, it is a square.
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 parallel sides but no right angles is called a parallelogram
A straight line
A RECTANGLE has 4 sides and 4 right angles.
This shape has only one pair of opposite sides and no right angles: <
If there are no angles, all you have is a 'straight side'. There is a plane and no shape. Maybe you are thinking that straight means standing up straight. You might then be thinking of an upright tube.
