Rhombus

Learn about rectangles, rhombi, and more!

In rhombi, the diagonals are always perpendicular

Find a rhombus' area using its diagonals

A rhombus is a quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length. The rhombus is often called a diamond, after the diamonds suit in playing cards, or a lozenge, though the latter sometimes refers specifically to a rhombus with a 45° angle.

A rhombus is a quadrilateral with all four sides equal in length.

This lesson will look at examples to explain geometric concepts.

This lesson will look at examples to give an explanation how to find the area of rectangles, parallelograms and rhombi in a couple of minutes with this lesson then sample questions solved for you.
