What is the sum of the interior angles of a 32 sided polygon?
5400 degrees
In geometry, a triacontadigon (or triacontakaidigon) or 32-gon is a thirty-two-sided polygon. In Greek, the prefix triaconta- means 30 and di- means 2. The sum of any triacontadigon’s interior angles is 5400 degrees.
What is the total interior angle of a regular polygon if T 20 triangles can be drawn inside the polygon?
3240 degrees
In geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon’s interior angles is 3240 degrees.
How many sides does a polygon have if the sum of the interior angles is 3960 {\ circ ∘?
The total number of degrees of the interior angles is given by (n-1)*180. n = 23 Your polygon has 23 sides.
How many sides does a polygon have if the sum of its interior angle 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 sum of interior angle 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 interior angle of a 19 sided polygon?

What is the sum of the interior angles in a regular pentagon?
Angles in a Pentagon
| General Rule | |
|---|---|
| Sum of Interior Angles of a polygon = | 180 ×(n−2) degrees, where n is number of sides |
| Measure of each of the Angle (in a Regular Polygon) = | 180 degrees ×(n−2) / n, where n is the number of sides/. |
How do you find the sides of a regular polygon when given the interior angle sum?
Answer: To find the number of sides of a polygon when given the sum of interior angles, we use the formula: Sum of interior angles = (n – 2) × 180, where n is the number of sides.
How do you find the measure of an interior angle of a regular polygon?
Lesson Summary 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.
What is the sum of the interior angles of a polygon?
The number of triangles is one more than that, so n-2. This can be used as another way to calculate the sum of the interior anglesof a polygon. The interior angles of a triangle always sum to 180°. The number of triangles is n-2 (above).
What is the sum of interior angles of a regular decagon?
To find the sum of interior angles of a polygon, multiply the number of triangles formed inside the polygon to 180 degrees. For example, in a hexagon, there can be four triangles that can be formed. Thus, 4 x 180° = 720 degrees. What is the measure of each angle of a regular decagon?
What is the measure of an angle in a regular polygon?
You might already know that the sum of the interior angles of a triangle measures 180 ∘ and that in the special case of an equilateral triangle, each angle measures exactly 60 ∘ . So, our new formula for finding the measure of an angle in a regular polygon is consistent with the rules for angles of triangles that we have known from past lessons.
How do you find the sum of interior angles of a triangle?
Each time we add a side (triangle to quadrilateral, quadrilateral to pentagon, etc), we add another 180° to the total: So the general rule is: Sum of Interior Angles = (n −2) × 180 ° Each Angle (of a Regular Polygon) = (n −2) × 180 ° / n
