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°

Does a polygon have more angles or sides explain?

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


Does a polygon usually have more sides or more angles example?

A polygon has an equal number of sides and angles. For example, a triangle has 3 sides and 3 internal angles.


Do all interior angles in a polygon add up to 180 degrees?

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.


What is the relation between a polygon's number of sides and sum of its interior angle?

sum of internal angles = 180(n-2) where n is the total number of sides of the polygon.


What is angel of eight sided polygon?

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.


How do you find the internal angle of a regular 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.


What is Equlangular polygon?

A polygon is equiangular if its internal angles are mutually equal to each other.


What are the internal angles of a tetradecagon?

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!


Is it true if a polygon has odd number of angles the angles cannot be congruent?

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.


What is the relationship between the number of sides and number of angles a polygon has?

A polygon has the same number of sides and angles.


How does a polygon have the same number of sides and 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.


Is there is relation between sides of polygon and angles of that polygon?

Yes. Internal angles of an n-sided regular polygon total 180n -360 degrees, usually expressed as (2n - 4) right angles
