## Quadrilaterals: Rhombus and Parallelogram

A rhombus is a quadrilateral with four equal sides and four equal angles. A parallelogram is a quadrilateral with two pairs of parallel sides. Difference Between Rhombus and Parallelogram.

## What is a Rhombus?

A rhombus is a parallelogram with four equal sides and four equal angles.

A rhombus is a parallelogram with four equal sides. The angles in a rhombus are all equal, and they are all in the same direction.

The length of a side of a rhombus is called the length of a rhombus. The formula for the length of a rhombus is

The length of a rhombus is equal to the sum of the lengths of the two shorter sides multiplied by the sine of the angle between them.

## What is a Parallelogram?

A parallelogram is a quadrilateral with two pairs of parallel sides.

A parallelogram is a quadrilateral with two pairs of parallel sides. The opposite angles are congruent, and the diagonals bisect each other.

There are four types of parallelograms: rectangular, square, rhombus, and trapezoid.

Rectangular parallelograms are the most common type. They have four right angles, and the lengths of their sides are proportional.

Square parallelograms are similar to rectangular parallelograms, but all of their angles are 90 degrees.

Rhombus parallelograms have four equal sides, but their angles are not all 90 degrees.

Trapezoid parallelograms have two parallel sides and two non-parallel sides. The angle between the parallel sides is called the base angle, and the angle opposite the base angle is called the apex angle.

## Difference Between Rhombus and Parallelogram

Parallelograms are quadrilaterals in which both pairs of opposite sides are parallel. Rhombuses are parallelograms with all angles equal.

A parallelogram is a four-sided figure with two pairs of parallel sides. A rhombus is a parallelogram with all sides of equal length.
