# Rectangle vs Trapezoid: Difference and Comparison

A quadrilateral is a two-dimension structure having four sides. Thus, a rectangle and a trapezoid are also quadrilaterals with prominent differences.

One may get confused between the two terms, and questions like these may arise: What are the differences between their structures? Are both of them parallelograms?

## Key Takeaways

1. Rectangles have four right angles and opposite sides of equal length, while trapezoids have only one pair of parallel sides.
2. Rectangles have two pairs of equal opposite sides, while trapezoids do not.
3. Rectangles have congruent diagonals, while trapezoids do not unless they are isosceles.

## Rectangle vs Trapezoid

A rectangle is a four-sided polygon with four right angles and opposite sides that are parallel and congruent. Its diagonals are equal in length and bisect each other at right angles. A trapezoid is a four-sided polygon with only one pair of parallel sides. The other two sides are not parallel and may be of different lengths. A trapezoid has two angles that are acute and two obtuse angles.

A rectangle is a quadrilateral with four right angles. The word rectangle is derived from the Latin ‘rectangulus’, which can be split into ‘rectus’, meaning right and ‘angulus’, meaning angle.

On the other hand, a trapezoid is a quadrilateral with a pair of parallel sides. The word trapezoid is derived from the Greek word ‘trapézion’, meaning a small table.

## What is Rectangle?

A rectangle is a quadrilateral, i.e. a four-sided figure with two parallel and equal opposite sides. It contains four 90° angles. The word ‘rectangle’ is derived from the Latin ‘rectangulus’, which can be split into ‘rectus’, meaning right and ‘angulus’, meaning angle.

The sum of any two adjacent angles in a rectangle equals 180°, and the sum of all the angles in a rectangle equals 360°.

A square can be considered a particular type of rectangle with equal sides. A rectangle is also a parallelogram since it has two parallel sides.

## What is Trapezoid?

A trapezoid is a quadrilateral having a pair of parallel opposite sides. Sometimes a trapezoid is strictly a quadrilateral having only a couple of parallel opposite sides.

The word ‘trapezoid’ is derived from the Greek word ‘trapézion’, meaning a small table. The diagonals in a trapezoid need not be equal.

A trapezoid is also called a trapezium many times. The sum of all the angles of a trapezoid also comes out to be 360°. A trapezoid may or may not have right angles in it.

## Main Differences Between Rectangle and Trapezoid

1. A rectangle is a quadrilateral with four right angles, two equal opposite sides and two parallel opposite sides. In contrast, a trapezoid is a quadrilateral with just a pair of parallel opposite sides.
2. The diagonals of a rectangle are equal and bisect each other, while the diagonals of a trapezoid aren’t equal and intersect.
