Solution:
A Polygon is said to be regular if it's all sides and all angles are equal.
And We define polygon as a simple closed curve entirely made up of line segments.
There are five types of Quadrilateral.
A.Quadrilateral regular→→Regular(Square)
1. Parallelogram 2. Rhombus 3. Square 4. Rectangle 5. Kite
Square is a regular polygon which is a quadrilateral.
2. Pentagon Regular is called Regular pentagon.→→Regular
3. Pentagon irregular means, not all sides as well as all angles equal.
4. Quadrilateral irregular are Parallelogram , Rhombus and kite.
