POLYGONS

• 

A polygon is any 2D shape that is closed and made up of straight lines. If it has curves or an open end, it’s not a polygon.

Characteristics of Polygons

• It is formed using three or more straight line segments.
• The line segments are called sides.
• The meeting point of two sides is called a vertex.
• Polygons have interior angles formed between the sides.
• The sides of a polygon do not intersect each other except at the vertices.
• Polygons have interior angles formed between the sides.
• The sides of a polygon do not intersect each other except at the vertices.
• The line segments are called sides.
• The meeting point of two sides is called a vertex.
• Polygons have interior angles formed between the sides.

Different Types of Polygons

Based on the number of sides:

• Triangle – 3 sides
• Quadrilateral – 4 sides
• Pentagon – 5 sides
• Hexagon – 6 sides
• Heptagon – 7 sides
• Octagon – 8 sides

Based on sides and angles:

• Regular Polygon – All sides and angles are equal.
• Irregular Polygon – Sides and angles are not equal.
