What is the measure of an angle of a regular polygon of 20 sides?
Answer: Each exterior angle of a regular polygon of 20 sides = 360/20 = 18 deg. Each interior angle of a regular polygon of 20 sides = 180 – 18 = 162 deg. Total sum of the 20 interior angles of the regular polygon = 162 × 20 = 3240 deg.
What is the sum of the interior angles of a 20-gon?
3240°
Icosagon/Sum of interior angles
How many sides does a polygon have if each exterior angle measures 20 degrees?
Step-by-step explanation: Each exterior angle of a regular polygon = 20 deg. So the polygon has 360/20 = 18 sides.
What is the sum of the interior angles in a 20 sided polygon if it is a regular polygon What would the measure of each interior angle be?
3240 degrees
The sum of the interior angles of a regular n-gon is given by the formula (n-2)180. Hence, in our case n=20 and we have the answer of 18(180)=3240 degrees.
How much more is the sum of the angles of a 20 sided polygon than a 12 sided polygon?
1,440° Now in the question we are asked to find How much more is the sum of the angle of a 20 sided polygon than a 12 sided polygon. So, We can just subtract the angle sum of 12 sided polygon from 20 sided polygon.
How do you work out the interior angle of a polygon with 20 sides?
Explanation:
- The internal angle measure of a triangle no matter the type is 180o.
- The 4 sided polygons (square being the most understood) has an interior angle measure of 4 x 90o or 360o.
- for an equilateral 20 sided polygon the equation is 360o20 = 18o.
How do you find the sum of a 20 sided polygon?
The formula for calculating the sum of the interior angles of a polygon is as follows:
- (n−2)⋅180.
- n is the number of sides of the polygon.
- In this case, we can plug in 20 to get the following:
- (20−2)⋅180.
- 18⋅180.
- 3,240.
How many degrees are in a 20-gon?
How much is each angle of a 20 sided regular polygon How much is each outer angle?
The regular icosagon has Schläfli symbol {20}, and can also be constructed as a truncated decagon, t{10}, or a twice-truncated pentagon, tt{5}. One interior angle in a regular icosagon is 162°, meaning that one exterior angle would be 18°.
How do you find the exterior angle of a 20-gon?
Thus, the sum of the exterior angles will be 360°. So, for a regular 20-gon, each exterior angle is 360°/20 = 18°.
What is the sum of the measures of all 20 exterior angles of a 20 sided polygon?
360∘
Therefore 20 -gon has 20 exterior angles whose sum is 360∘ .

How many sides does a regular polygon have?
Each exterior angle of a regular polygon measures 20. How many sides does the polygon have? A very useful property to know of any polygon, whether regular or irregular, is that the sum of the exterior angles is always 360°.
Is the icosagon a 20-sided polygon or a pentagon?
In geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon’s interior angles is 3240 degrees. The regular icosagon has Schläfli symbol {20}, and can also be constructed as a truncated decagon, t {10}, or a twice-truncated pentagon, tt {5} .
How to find the size of a polygon’s exterior angle?
For a regular polygon, the size of each exterior angle, θ can be found from: θ = 360° n ← where n = number of sides Using this property, if you know the size of the exterior angle, you can find the number of sides. n = 360° 20°
What is the sum of interior angle measure of a 20-gon?
In geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon ‘s interior angles is 3240 degrees.
