Vedantu Selina Solutions for Class 6 Chapter 28 Polygons will help students to understand the concepts of Polygons. Before jumping to solve the problems on Polygons let us revise the important concepts and formulas of Polygons.

What is Polygon?

A polygon is a simple closed curve. A 2D closed figure bounded with three or more than three straight lines is called a polygon. Triangles, square, rectangle, pentagon, hexagon, are some examples of polygons.

The segments are referred to as the sides of the polygon. The points at which the segments meet are called vertices. Segments that share a vertex are called adjacent sides. A segment joining the nonadjacent vertices is called a diagonal. 

Types of Polygons

Different types of polygons are as follows:

• Regular Polygon

• Irregular Polygon

• Convex Polygon

• Concave polygon

Regular Polygon

Polygons whose sides and angles are of equal lengths are called regular polygons.

Irregular Polygon

Polygons with different sizes and different interior angles are called irregular polygons.

Convex Polygon

Polygons with interior angles less than 1800 are called convex polygons.

Concave Polygons

Polygons with interior angles greater than 1800 are called concave polygons.

Regular Polygon Formulas

Some of the Regular Polygon Formulas Related to Polygons are:

• Interior Angle: An angle inside the polygon at one of its vertices is called the interior angle. Angle Q is an interior angle of quadrilateral.

• Exterior Angle: An angle outside the polygon formed by one of its sides and the extension of an adjacent side is called the exterior angle of the quadrilateral.in the above quadrilateral angle ADZ, YUA, YUX, and QUX are the exterior angles.

• The sum of the measures of all the exterior angles of a polygon is 360°.

• Interior angle + corresponding exterior angle = 1800

• The sum of the measures of the interior angles of a polygon with n sides is given by the general formula  (n–2)180.

Sum of Interior angles of Polygon(IA) = (n-2) x 180

• The measure of an exterior angle of a regular n - sided polygon is given by the formula 360/n 

Exterior angle of a regular polygon(EA) = 360/n

• The measure of an interior angle of a regular n- sided polygon is \[\frac{(n-2)180}{n}\]

Interior angle of a regular polygon = \[\frac{(n-2)180}{n}\]

• The number of diagonal of n- sided polygon is \[\frac{n(n-3)}{2}\]

Diagonal of Polygon = \[\frac{n(n-3)}{2}\]

• Perimeter P of a regular n-sided Polygon with s as the length of the sides is given by n x s  

Perimeter of Polygon(P) = n x s

• Area of polygon formula of a regular n-sided polygon with s as the length of the sides is given by s/2tan(180/n)

Area of Polygon(A) = s/ 2 tan (180/n)
