A quadrilateral is a polygon that has exactly four sides. (This also means that a quadrilateral has exactly four vertices, and exactly four angles.)

Area l × b l × h
Perimeter 2 × (l + b) 2 × (l + b)

## How do you identify a quadrilateral?

All sides are of equal length. There are four right angles. There are four sides because it’s a quadrilateral.

## What is a quadrilateral line?

A quadrilateral is a plane figure made with four line segments closing in a space. If you connect the four linear objects at their eight ends, you have a quadrilateral, a four-sided polygon. Maybe you arranged four sides so the shape looks full, which means you made a convex quadrilateral.

## What is the best definition of a quadrilateral?

In geometry, a quadrilateral can be defined as a closed, two-dimensional shape which has four straight sides. The polygon has four vertices or corners.

## What is a quadrilateral for kids?

## What is quadrilateral and its types?

Answer: A quadrilateral refers to a four-sided polygon that has four angles. The seven types of quadrilaterals are parallelogram, rhombus, kite, rectangle, trapezoid, square, and isosceles trapezoid. Answer: A trapezoid refers to a 4-sided flat shape with straight sides and it has a pair of parallel opposite sides.

## Is a cube a quadrilateral?

Four sided figures are called quadrilaterals. A quadrilateral with opposite sides equal and parallel is called a parallelogram. A rectangle with all its sides equal is called a square, which is, in 3d, a cube.

## What is the correct name for a quadrilateral?

Parallelogram is the proper name of the quadrilateral.

A quadrilateral is a 4-sided two-dimensional shape. There are 4 types of quadrilaterals: parallelograms, trapezoids, rectangles, and rhombuses. A rectangle has 4 right angles. A rhombus is a quadrilateral with all 4 sides of the same length.
