Quadrilaterals are a crucial component of the arithmetic curriculum in schools, colleges, and even universities. However, while working on related topics, most pupils frequently question, “What is a quadrilateral?”

Students must grasp the fundamentals of the quadrilateral to comprehend geometry. Any four points can be linked to create this closed shape. It’s crucial to remember that only three points are non-colinear in this situation. Latin defines quadrilateral as having four sides. Quadra, thus, denotes four, and lateral, having sides.

## Quadrilaterals’ Qualities

Even quadrilaterals have qualities, just like every other geometrical form. As follows:

- with four edges or sides.
- having four corners or vertices.
- 360-degree interior angles are all together.
- Although these are quadrilaterals’ fundamental characteristics, it is important to remember that other kinds of quadrilaterals also have additional characteristics. Let’s examine the several kinds of quadrilaterals that may be found nowadays.

## Quadrilateral Types

There are several common varieties of quadrilaterals, including:

### Square

The angles on each square’s four equal sides are 90 degrees. A square’s diagonals are parallel to one another as well. Two of its diagonals are also equal. The diagonals are at right angles to one another and also perpendicular to one another.

### Rectangle

A quadrilateral with two pairs of parallel, equal sides is a rectangle. Additionally, they all feature 90-degree angles. It also has two equal diagonals that are at right angles to one another.

#### Trapezium

Two opposites are parallel to one another in a trapezium. Additionally, they could have various angles that together total 360 degrees.

#### Rhombus

A rhombus has four sides, each of which is the same length. On the other hand, opposing sides are parallel, and opposing angles are equal. A rhombus’ diagonals also come together at straight angles or 90 degrees.

#### Kite

Each side of a kite is divided into two pairs, each of which has two sides of equal length. The line drawn by the two pairings always joins at a right angle. A kite’s diagonal divides the other in two.
