Best Answer

If all of the interior angles of the polygon add up to 180 degrees,

then the polygon is a triangle.

The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 6660 degrees.

The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 135 degrees

Here is the formula- (Number of sides -2) x180 degrees = angle sum. The sum of the interior angles inside of a polygon will be 180*(n-2) degrees, where n=number of sides of the polygon. Example: a triangle has 3 sides; therefore, the sum of the angles inside will be equal to 180*(3-2)=180*(1)=180 degrees.

A twenty-sided polygon is called an "icosagon" If it is a regular icosagon - all its sides and angles are equal - then it's interior angles are all 162 degrees. You can verify this by drawing a line to the centre from each angle.. There will be 20 small angles arranged in a circle around the centre. These must total 360 degrees. As 360 / 20 = 18, this leaves the other angles of each triangle to add up to 162, because the interior angles of a triangle total 180 degrees.

It will have 2 opposite equal angles of 33 degrees and 2 opposite equal angles of 147 degrees
