Rhombus

A rhombus is a four-sided polygon with opposite sides parallel and all sides the same length.

Properties of a Rhombus

• A rhombus is equilateral. All sides are the same length.
• Opposite sides of a rhombus are parallel.
• All rhombuses are polygons.
• All rhombuses are quadrilaterals.
• All rhombuses are parallelograms.
• Squares are special cases of a rhombus whose sides meet at right angles.
• The opposite angles of a rhombus are congruent.
• The diagonals of a rhombus bisect each other.
• Each diagonal bisects the rhombus into two congruent triangles.
• The sum of the angles of a rhombus is 360° or 2π radians.
• A tiling of a plane can be created using any rhombus.
• The area of a rhombus is A = bh where A is the area, b is the base and h is the height.
