What is the sum of the interior angles of the polygon shown below?

Given:

The number of sides of given polygon = 4

To find the sum of the interior angles of the polygon.

Formula

The sum of interior angles of any polygon is

where, n be the number of sides of the polygon.

Now,

Taking n = 4 we get,

or,

or,

Hence,

The  sum of the interior angles of the polygon is 360°.
