What shape has equal sides and all sides are equal?

A square has equal sides (marked “s”) and every angle is a right angle (90°) Also opposite sides are parallel. A square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length). The Rhombus. A rhombus is a four-sided shape where all sides have equal length (marked “s”).

What shape has opposite sides that are equal?

The Square. Also opposite sides are parallel. A square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length). The Rhombus.
