What is the sum of the interior angles of the polygon? OA. 450 O B. 90° O C. 180° OD. 360°

Sagot :

The general formula to know how much is the sum of the interior agles of a polygon is:

[tex](n-2)\cdot180º[/tex]

Where n is the number of sides.

Then:

In a polygon with 3 sides the internal angles sum: 180º

[tex](3-2)\cdot180º=180º[/tex]

In a polygon with 4 sides the internal angles sum: 360º

[tex](4-2)\cdot180º=360º[/tex]

In a polygon with 5 sides the internal angles sum: 540º

[tex](5-2)\cdot180º=540º[/tex]
