How do you find the smallest interior angles of a polygon?
Once you know how to find the sum of interior angles of a polygon, finding one interior angle for any regular polygon is just a matter of dividing. Next, divide that sum by the number of sides: measure of each interior angle = Sn. measure of each interior angle = 1,080°8.
How do you find the largest interior angles of a polygon?
We multiply 30 times 4 to find the biggest angle. Since 30 times 4 = 120, the biggest angle is 120 degrees. Likewise, the other angles are 3*30=90, 3*30=90, and 2*30 = 60.
Are the interior angles of a polygon 360?
A special rule exists for regular polygons: because they are equiangular, the exterior angles are also congruent, so the measure of any given exterior angle is 360/n degrees. As a result, the interior angles of a regular polygon are all equal to 180 degrees minus the measure of the exterior angle(s).
What is the sum of the interior angles of a 9 sided polygon?
The General Rule

Any Polygon | n | (n−2) × 180° |
What is the largest interior angle of polygon?
The triacontagon is the largest regular polygon whose interior angle is the sum of the interior angles of smaller polygons: 168° is the sum of the interior angles of the equilateral triangle (60°) and the regular pentagon (108°).
How many sides does a polygon have if the sum of the interior angles is 360?

Hexagon | 6 | 720° |
How many interior angles does a Nonagon have?
9 angles
A nonagon consists of 9 angles. The sum of angles of a nonagon is 1260°.
How many interior angles does a decagon have?
ten angles
In geometry, a decagon (from the Greek δέκα déka and γωνία gonía, “ten angles”) is a ten-sided polygon or 10-gon. The total sum of the interior angles of a simple decagon is 1440°….Decagon.

How many sides are on a regular tetradecagon?
A regular Tetradecagon where the length of each side is 2 units. The units may either be inches or cm or km or miles: any unit of length. You are given a Regular Polygon with 14 sides.
How is the sum of interior angles of a tetradecagon expressed?
It is usually expressed in the form of integrals ∮ (p 2dѡ/2) in polar coordinates p, ∮ or ∮y dx in Cartesian coordinates x, y, where the end of the radius vector p or ordinate y traverses the path once. The sum of the interior angles of any nonself-intersecting polygon with n sides is equal to (n — 2)180°.
How are interior and exterior angles of a polygon related?
Exterior angles of a polygon are the angles at the vertices of the polygon, that lie outside the shape. The angles are formed by one side of the polygon and extension of the other side. The sum of an adjacent interior angle and exterior angle for any polygon is equal to 180 degrees since they form a linear pair.
How to calculate the interior angles of a pentagon?
For a regular pentagon, each angle will be equal to: 540°/5 = 108° 108°+108°+108°+108°+108° = 540° Sum of Interior angles of a Polygon = (Number of triangles formed in the polygon) x 180°
