What is the formula for the sum of the interior angles of a polygon

andrey2020 [161]

Answer:

Sum of the interior angles = (n-2) x 180°

where

n is the number of sides of the polygon

Step-by-step explanation:

The formula for the sum of the interior angles of a polygon is:

$sum=(n-2)*180$

where

$sum$ is the sum of the interior angle of the polygon

$n$ is the number of polygons

Let's check the formula using an example:

We want to find the sum of the interior angles of a square, we know that a square has 4 sides, so $n=4$ .

Replacing values

$sum=(4-2)*180$

$sum=(2)*180$

$sum=360$

We can apply the same procedure to any convex polygon with n sides.
