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.
