How many sides has a polygon if its angles is 26 right angles?
The sum of the angles of any polygon (of n sides) is 2n – 4 rt-angles. Your polygon’s angles have a sum of 26 rt-angles, we now have 2n – 4 = 26, adding 4 to both sides, we have 2n = 30, or n (the number of sides) = 15.

How do you find the sum of the interior angles of a 25 sided polygon?
Now , to find the measure of each interior angle of a regular 25-sided polygon we will divide the sum of all interior angles of a 25-sided polygon by the number of sides -25 . The measure of each interior angle of a regular 25-sided polygon =4140∘25=165.6∘. Therefore , the required answer is 165.6∘.
How do you calculate the angles in a polygon?
The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides. The sum of exterior angles of a polygon is 360°. The formula for calculating the size of an exterior angle is: exterior angle of a polygon = 360 ÷ number of sides.
How many diagonals can be drawn in a polygon of 26 sides?
diagonals, as each vertex has diagonals to all other vertices except itself and the two adjacent vertices, or n − 3 diagonals, and each diagonal is shared by two vertices….Polygons.
| Sides | Diagonals |

| 26 | 299 |
How many sides has a polygon if the sum of interior angles of that polygon gives 3240?
Answer and Explanation: The number of sides for a regular polygon that has 3240 degrees for the some of their interior angles is 20.
What is the sum of the exterior angles of a 25 sided polygon?
Explanation: Sum of the measures of all the exterior angles of any polygon, irrespective of its number of sides is always 360∘ .
What is the sun of the exterior angles of a 25 gon?
I figured it out by doing: 360/25 = 14.4.
What is the sum of all the interior angles of a 24 sided polygon?
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.
What is the formula to find the diagonal of a polygon?
Number of Diagonals = n(n-3)/2 This formula is simply formed by the combination of diagonals that each vertex sends to another vertex and then subtracting the total sides. In other words, an n-sided polygon has n-vertices which can be joined with each other in nC2 ways.
What is the sum of the interior angles for a 24 Gon?
What is the sum of the interior angles of a polygon with 20 sides?
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.
What does a Megagon shape look like?
A megagon or 1,000,000-gon is a polygon with one million sides (mega-, from the Greek μέγας, meaning “great”, being a unit prefix denoting a factor of one million).
What is the angle sum of a undecagon?

What is the sum of the interior angles of a 24 Gon?
What is the formula for a regular polygon with n sides?
Regular Polygon Formula For a regular polygon of n sides, we have: Each exterior angle = 360 o n Each interior angle = 180 o – (e a c h e x t e r i o r a n g l e)
What is the sum of the angles of a convex polygon?
The sum of the measures of the interior angles of a convex polygon with n sides is (n − 2) ⋅ 180 ∘.
What are the sides of a polygon called?
Each straight line in a polygon is called its side. A triangle, quadrilateral, pentagon, hexagon, heptagon, octagon, nonagon, and decagon are called a polygon accordingly as it contains 3, 4, 5, 6, 7, 8, 9, 10 sides, respectively. Adjacent sides of a polygon are the ones whose two sides have a common end-point (vertex).
What is true about the sum of interior angles of a polygon?
