Find the measure of one interior angle of a regular polygon with 18 sides.Sum of Interior Angles of a Regular Polygon. Let there be a n sided regular polygon. Since, the sides of a regular polygon are equal, the sum of interior angles of a regular polygon = (n − 2) × 180° For example, the sides of a regular polygon are 6. So, the sum of interior angles of a 6 sided polygon = (n − 2) × 180° = (6 − 2) × 180 ...The sum of the interior angles of a polygon can be found by taking the number of sides (n) and subtracting 2. Then, multiply that number by 180. Sum of interior angles = (n – 2) ∙ 180° To find the measure of each interior angle in a regular polygon: 1. To find the measure of one interior angle in a regular polygon, first find the sum of ...Solution. The correct option is B 540 degrees. Sum of interior angles of a polygon = (n-2)*180⁰. Pentagon has 5 sides, so n = 5. Therefore, Sum of interior angles of a pentagon = (5-2) *180⁰. Sum of interior angles of a pentagon = 540⁰. Suggest Corrections. 1.

A triangle has three sides. Therefore n = 3. Using the formula to calculate the interior angle sum would be calculated as follows: (n - 2)180°. (3 - 2)180° 1 x 180° = 180°, as expected. The sum of the interior angles of each polygon are shown in the table below: Notice the sum increases by 180° for each polygon.Find the sum of the interior angles of a nonagon.
