### Theory:

A quadrilateral is a closed figure of precisely four sides.
There are many types of quadrilaterals. As the word ‘quad’ means four, all these types of a quadrilateral have four sides, and the sum of angles of these shapes is $$360$$ degrees.

1. Square

2. Rectangle

3. Parallelogram

4. Rhombus

5. Trapezium

Let us look at the properties of each of these quadrilaterals in detail.
