What are the formulas for polygons?
Polygon Formula
- The sum of interior angles of a polygon with “n” sides =180°(n-2)
- Number of diagonals of a “n-sided” polygon = [n(n-3)]/2.
- The measure of interior angles of a regular n-sided polygon = [(n-2)180°]/n.
- The measure of exterior angles of a regular n-sided polygon = 360°/n.

What is polygon BYJU’s?
A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end. The line segments of a polygon are called sides or edges.
What is Apothem in polygon?
The apothem (sometimes abbreviated as apo) of a regular polygon is a line segment from the center to the midpoint of one of its sides. Equivalently, it is the line drawn from the center of the polygon that is perpendicular to one of its sides. The word “apothem” can also refer to the length of that line segment.
Which polygon has 4 sides?
Definition: A quadrilateral is a polygon with 4 sides. A diagonal of a quadrilat- eral is a line segment whose end-points are opposite vertices of the quadrilateral.
How many sides a polygon has formula?
Answer: To find the number of sides of a polygon when given the sum of interior angles, we use the formula: Sum of interior angles = (n – 2) × 180, where n is the number of sides.
Is Star a polygon?
By geometrical definition, a star is a regular polygon: simple or complex. Polygon – any two-dimensional shape formed with straight lines and is closed. A convex polygon is defined as a polygon with all its interior angles less than 180°. Otherwise, the polygon is concave.
