Divide 360 by the number of sides, then subtract the quotient from 180 to get the angle in degrees.
A 6 sided shape (hexagon) would have 6 interior angles of 120 degrees (assuming it is regular)
Each interior angles measures 165 degrees
A 12 sided shape with equal sides and with equal interior and exterior angles
Providing that it's a regular 27 sided polygon then the interior angles add up to 4500 degrees and each interior measures 166o40'0''
A regular 5 sided pentagon has 5 interior obtuse angles each measuring 108 degrees.
Any angle that you like. It is only if the shape is regular that you can make any more precise statements.
The interior angles of a 24 sided shape add up to 3960 degrees
The formula for the sum of the interior angles of a shape with n sides is: 180 * (n - 2) So, for a 31 sided shape, the sum of the interior angles is 180 * 29 = 5,220.
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 900 degrees
The equation for the total interior angles of a polygon is (n-2)x180. In this case, the shape has 56 sides. Thus, to work out the total interior angles of the shape you do: (56-2)x180 =54x180 =9,720. Therefore the total interior angles for a 56 sided shape is 9,720.
A regular or an irregular decagon is a ten sided shape that has 10 interior angle that add up to 1440 degrees.
