A polygon is a closed figure that is composed of straight sides, known as line segments. Each line segment intersects with exactly two other segments, with no crossings or self-intersections. The word polygon is derived from the Greek words “poly” meaning “many” and “gonia” meaning “angle”.

Polygons can be classified based on the number of sides they have. Here are some common types of polygons:

1. Triangle: A triangle is a polygon with three sides. It can be further classified into different types based on its angles and side lengths, such as equilateral, isosceles, or scalene triangles.

2. Quadrilateral: A quadrilateral is a polygon with four sides. Some examples of quadrilaterals are squares, rectangles, parallelograms, and trapezoids.

3. Pentagon: A pentagon is a polygon with five sides.

4. Hexagon: A hexagon is a polygon with six sides.

5. Heptagon: A heptagon is a polygon with seven sides.

6. Octagon: An octagon is a polygon with eight sides.

7. Nonagon: A nonagon is a polygon with nine sides.

8. Decagon: A decagon is a polygon with ten sides.

The sum of the interior angles of an n-sided polygon can be found using the formula: (n – 2) * 180 degrees. For example, a triangle has three sides, so the sum of its interior angles would be (3 – 2) * 180 = 180 degrees. Similarly, a quadrilateral has four sides, so the sum of its interior angles would be (4 – 2) * 180 = 360 degrees.

To calculate the exterior angle of a regular polygon, you can use the formula: 360 degrees / n, where n represents the number of sides. For instance, for a hexagon, the exterior angle would be 360 / 6 = 60 degrees.

Polygons have various properties and characteristics. They can be classified based on their symmetry, regularity, and the lengths of their sides and angles. Additionally, polygons can be used in real-life applications such as measuring land area, creating architectural designs, and solving geometric problems in mathematics.
