Each interior angle of the regular 8 sided octagon measures 135 degrees
Each interior angle measures 162 degrees.
Each interior angle: 140 degrees Each exterior angle: 40 degrees
360/number of sides and deduct the quotient from 180 which will give the measure of each interior angle
180-interior angle = exterior angle If it's a regular polygon then: 360/number of sides = exterior angle
If its a regular polygon then 180-interior angle and divide the answer into 360 which will give the number of sides of the polygon.
that's geometry so the formula to find the measure of each interior angle of a regular polygon is: Ia=stands for internal angle Ia=(n-2)180 ---------- n that's the formula.
You use the fact that the sum of the interior angles of a regular polygon with n sides is:180(n-2) degreesNow you have the sum of measures of all the interior angles so divide that by n and you have the measure of each interior angle.
Its interior angles are: (10-2)*180 = 1440 degrees If its a regular 10 sided polygon then each interior angle is: 1440/10 = 144 degrees
