The addition of an extra side increases the total of the internal angles by 180°
The sum of the internal angles of a polygon = (number of sides - 2) × 180°
An eight-sided polygon, or octagon, has internal angles that sum to 1,080 degrees. Each internal angle of a regular octagon measures 135 degrees, as it is calculated by dividing the total sum of the internal angles (1,080 degrees) by the number of angles (8). Therefore, in a regular octagon, each angle is equal and contributes to the polygon's symmetrical shape.
A polygon is equiangular if its internal angles are mutually equal to each other.
No, it is not true that a polygon with an odd number of angles cannot have congruent angles. A polygon can have an odd number of angles and still have some or all of them be congruent. For example, a regular pentagon has five angles that are all congruent, and a polygon with an odd number of sides can also have pairs of congruent angles.
i don't really get the "same number of sides" ----- the angles of a polygon are the same with other angles within the polygon, if it is a regular polygon, and there a formula for getting the total sum of angles which is 180X(N-2) where N is the number of sides.
Yes. Internal angles of an n-sided regular polygon total 180n -360 degrees, usually expressed as (2n - 4) right angles
A polygon has exactly the same number of both internal and external angles to the number of sides. Assuming external angles count, there are two times the number of sides as the total number of angles
A polygon has an equal number of sides and angles. For example, a triangle has 3 sides and 3 internal angles.
No. The sum of the internal angles of a polygon is related to the number of sides involved. The formula for calculating this sum is 180° × (n - 2) where n is the number of sides in the polygon.
sum of internal angles = 180(n-2) where n is the total number of sides of the polygon.

you add the other 3 internal angles together and take the answer away from 180 and the number that is left is your answer.
A polygon is equiangular if its internal angles are mutually equal to each other.
a tetradecagon is a polygon with 14 sides. Deca = 10, and tetra = 4. The formula for the internal angle for a polygon is 180 * (n - 2) / n, where n is the number of sides on the polygon. You should be able to figure out the rest from there!
