What is the degrees for an angle of a regular octagon?

The sum of angles in degree = 180(n - 2), where n is the number of sides of the regular polygon. The sum of angles in degree = 180(n - 2); n = 8 The sum of angles in degree = 180(8 - 2) = 180(6) = 1,080 Angle in degree = (The sum of angles in degree)/n Angle in degree = (1,080)/8 = 135 Thus, in a regular octagon, the degree of an angle is 135.


Degree of an angle in a regular octagon?

The sum of angles of a regular polygon in degrees = 180(n - 2), where n is the number of sides of the regular polygon. So, where n = 8 the sum of angles in degree = 180(8 - 2) = 180(6) = 1,080 Angle in degree = (The sum of angles in degree)/n Angle in degree = (1,080)/8 = 135 Thus, in a regular octagon, the degree of an angle is 135.

What is each interior angle measure of a regular pentagon?

180 degree( 5-2) is the sum of the interior angles. Now divide this by 5 since it is regular and that tells us all the angles have the same measure.


What is the sum of angles in octagon?

Sum of angles in a regular polygon = (#sides - 2) * 180. Sum of Octagon angles = (8-2) * 180 = 1080
