## What is the sum of the interior angles of a 17 sided polygon?

2700°
The sum of the interior angles of a 17-sided convex polygon is 2700°, and the sum of the exterior angles is 360°.

## What is the sum of the interior angles of an 18 sided polygon?

The sum of the measures of the interior angle of any polygon is the number of sides minus 2 multiplied by 180. A polygon with 18 sides has an interior angle sum of 2880 degrees.

## How to find the sum of the interior angles of a polygon?

Sum of Interior Angles of a Polygon. The Sum of interior angles of a polygon is always a constant value. If the polygon is regular or irregular, the sum of its interior angles remains the same. Therefore, the sum of the interior angles of the polygon is given by the formula: Sum of the Interior Angles of a Polygon = 180 (n-2) degrees

## How to calculate the interior angles of a pentagon?

For a regular pentagon, each angle will be equal to: 540°/5 = 108° 108°+108°+108°+108°+108° = 540° Sum of Interior angles of a Polygon = (Number of triangles formed in the polygon) x 180°

## What is the measure of one interior angle of a regular 15?

In a 15 -sided polygon: Sum interior angles = 180(15 − 2) = 180 × 13 = 2340° Each interior angle of the regular polygon = 2340° 15 = 156°

## What is the sum of the interior angles of an ABCDE?

In a polygon of ‘n’ sides, the sum of the interior angles is equal to (2n – 4) × 90°. ABCDE is a “n” sided polygon. Take any point O inside the polygon. Join OA, OB, OC. For “n” sided polygon, the polygon forms “n” triangles. Note: In a regular polygon, all the interior angles are of the same measure.
