## What is the sum of interior angles of a polygon?

To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°. The formula for calculating the sum of interior angles is ( n − 2 ) × 180 ∘ where is the number of sides. All the interior angles in a regular polygon are equal.

What is the sum of the interior angles of a 24 Gon?

3960 degrees
In geometry, an icositetragon (or icosikaitetragon) or 24-gon is a twenty-four-sided polygon. The sum of any icositetragon’s interior angles is 3960 degrees.

### How do you find the sum of the measures of the interior angles of a polygon?

A regular polygon is a flat shape whose sides are all equal and whose angles are all equal. The formula for finding the sum of the measure of the interior angles is (n – 2) * 180. To find the measure of one interior angle, we take that formula and divide by the number of sides n: (n – 2) * 180 / n.

Is the sum of the interior angles of a polygon 360?

The sum of the interior angles of a regular polygon with n sides is 180(n-2). So, each interior angle has measure 180(n-2) / n. Each exterior angle is the supplement to an interior angle. Sum of exterior angles = n(360 / n) = 360.

## What is the sum of all interior angles of a 5 sided polygon?

540
Sum of Interior Angles of a Polygon with Different Number of Sides:

Regular Polygons
Polygon No. of Sides Sum of Interior Angles
Triangle 3 1800
Pentagon 5 5400

What is the interior angle sum of a 7 sided polygon?

Definition of Heptagon Since, heptagon has 7 sides therefore, Sum of interior angles = (n – 2) × 180°

### What is the sum of the interior angles of a 21 gon?

around 162.86∘
The interior angle of a regular 21-gon is around 162.86∘ .

What is the sum of the interior angles of a 20 gon?

3240°
Icosagon/Sum of interior angles

## What is the sum of the interior angles of a six sided polygon?

720 degrees
Explanation: The sum of the interior angles of a hexagon must equal 720 degrees. Because the hexagon is regular, all of the interior angles will have the same measure. A hexagon has six sides and six interior angles.

How do you find the interior angle sum of a 7 sided polygon?

### How many sides does a polygon have if the sum of interior angles is 360?

What is true about the sum of interior angles of a polygon?

Shape Formula Sum Interior Angles
3 sided polygon (triangle) (3−2)⋅180 180∘
4 sided polygon (quadrilateral) (4−2)⋅180 360∘
6 sided polygon (hexagon) (6−2)⋅180 720∘

What is the name of a regular polygon if its sum of interior angles is equal to 360?

The General Rule

Shape Sides Sum of Interior Angles
Pentagon 5 540°
Hexagon 6 720°
Heptagon (or Septagon) 7 900°

## How to find the sum of interior angles of a polygon?

13 sides Number of sides n =13 The sum of interior angles of polygon = (2n−4)×90o = (2×13−4)×90o

How to calculate the interior angles of a dodecagon?

The interior angles of a dodecagon are a bit harder. You can use this generic formula to find the sum of the interior angles for an n -sided polygon (regular or irregular): Sum of interior angles = ( n -2) x 180°. Sum of interior angles = 10 x 180° = 1800°. Once you know the sum, you can divide that by 12 to get the measure of each interior angle:

### How to find the sum of 13 sides of a polygon?

13 sides Number of sides n =13 The sum of interior angles of polygon = (2n−4)×90o = (2×13−4)×90o = (26−4)×90o = 22×90o We get, = 1980o.

What are the properties of a dodecagon polygon?

A dodecagon is a type of polygon with these properties: No matter the shape, a regular polygon can have its exterior angles add to no more than 360°. Think: to go around the shape, you make a complete circle: 360°. So, divide 360° by the dodecagon’s twelve exterior angles.
