You cannot calculate interior angles in a polygon. You can only calculate their sum. The sum of all the interior angles of an n-sided polygon is (n-2)*180 degrees. So for example, the interior angles of a triangle (n = 3) sum to 180 degrees. But the individual angles can be (1,1,178), or (30,60,90) or infinitely many other combinations.

-- Measure, calculate, or somehow get the measure of each interior angle. -- Add them all up to get one number which is their sum. -- That one number is the sum of the interior angles.

hmm * * * * * The sum of the interior angles of an n-sided polygon is 180*(n-2) degrees. IF the polygon is equiangular, then each angles is the above sum divided by n.

180n - 360 for any n-sided polygon (or 2n - 4 right angles)

The sum of all the interior angles of a triangle is 180 degrees while the sum of the exterior angles is 360. you can calculate for the measurements of the interior angles of a polygon by using the formula S=(n-2)(180) where n is the number of sides

(17-2)*180 = 2700 degrees

The sum of interior angles in an n- sided polygon is 180(n - 2) [number of sides minus two, then multiply by 180].

900 degrees.Explanation: The sum of the measures of the interior angles of a heptagon is 900°. A heptagon has 7 sides. So to calculate the sum of the measures of the interior angles in a heptagon, substitute 7 for n in (n − 2) • 180°. You get (7 − 2) • 180°, or 5 • 180°= 900°.

(number of sides-2)*180 = total sum of interior angles

The sum of the interior angles of a 24 sided shape is 180*(24 - 2) = 180*22 = 3960 degrees. If all the angles of the shape are equal then each one is 3960/24 = 165 degrees.

Yes. "Alternate interior" angles are always interior. Angles that are not interior as well as alternate are never accurately described as "alternate interior" angles.

yes a hexagon does have interior angles......
