. The sum of the interior angles of a pentagon is

Best Answer

Explanation:

A pentagon is made up of three triangles, the sum of their angles is = 3×180º =540º.

The total of the pentagon's interior angles can alternatively be calculated as follows:

The sum of the interior angles of a polygon with  sides equals =( n-2)×180º.

A pentagon has five sides, its interior angles are equal to =(5-2)×180º[ where n=5 ]=3×180º=540º.

Final Answer:

Hence, the sum of a pentagon's interior angles is 540º.
