Define Quadrilaterals.

Hi Mansi,

In geometry, a quadrilateral can be defined as a closed, two-dimensional shape that has four straight sides. 

A polygon has four vertices or corners.

For example,

Square, rectangle, rhombus, parallelogram, kite are all quadrilaterals.

We can find the shape of quadrilaterals in various things around us, like in a chessboard, a deck of cards, a kite, etc.
