What is the sum of the measures of the interior angles of a 13 sided polygon?

Question 130236: What is the sum of the measures of the interior anles of a convex 13 -gon? There is a formula the sum of the measures of the interior angles of a convex n-gon is (n-2)180 degrees. For a triangle, n=3, so it’s (1)180=180 degrees.

What is the sum of the measure of the interior angles of a 14 Gon?

The sum of the interior angles of a 14-gon = (14-2)*180 = 2160 degrees .

What is the interior angle sum of a 12 sided polygon?

1800 degrees

What is the formula for interior angles?

An interior angle is located within the boundary of a polygon. The sum of all of the interior angles can be found using the formula S = (n – 2)*180. It is also possible to calculate the measure of each angle if the polygon is regular by dividing the sum by the number of sides.

What is the sum of the interior angles of a 15 Gon?

Each triangle has an angle sum of 180 degrees , so the sum of the interior angles of the 15-gon must be 13 × 180 = 2340 degrees . Since the 15-gon is regular, this total is shared equally among the 15 interior angles. Each interior angle must have a measure of 2340 ÷ 15 = 156 degrees . an octagon we can draw 5 diagonals.
