How To Find The Measure Of One Interior Angle Of A Regular Octagon. The measure of each interior angle of a regular polygon is equal to the sum of interior angles of a regular polygon divided by the number of sides. Since we know that the sum of interior angles of octagon is.
A regular polygon is a flat shape whose sides are all equal and whose angles are all equal. The measure of an interior angle of a regular polygon is 144. A decagon is a 10 sided polygon with 10 interior angles and 10 vertices which is where the sides meet.
In a regular octagon each angle measures 135 degrees.
Below is the formula to find the measure of any interior angle of a regular polygon n number of sides. To find the measure of an interior angle of a regular octagon which has 8 sides apply the formula above as follows. 180 n - 360 n We know that all heptagons or septagons have 7. First lets see what the total angle of all the interior corners is of these pol.
