this pdf covers types of quadrilaterals and their property. n geometry a quadrilateral is a four-sided polygon, having four edges and four corners. The word is derived from the Latin words Quadri, a variant of four, and latus, meaning "side".

1.
What is 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.

We can find the shape of quadrilaterals in various things around us, like in a chess board, a deck

of cards, a kite, a tub of popcorn, a sign board and in an arrow.

Properties of a Quadrilateral:

● A quadrilateral has 4 sides, 4 angles and 4 vertices.

● A quadrilateral can be regular or irregular.

● The sum of all the interior angles of a quadrilateral is 360°.

Types of Quadrilaterals

Quadrilaterals can be classified into Parallelograms, Squares, Rectangles and Rhombuses.

Square, Rectangle and Rhombus are also Parallelograms.

Here’s a list of the types of quadrilaterals with their name, pictures and properties:
