The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 135 degrees
Here is the formula- (Number of sides -2) x180 degrees = angle sum. The sum of the interior angles inside of a polygon will be 180*(n-2) degrees, where n=number of sides of the polygon. Example: a triangle has 3 sides; therefore, the sum of the angles inside will be equal to 180*(3-2)=180*(1)=180 degrees.
A twenty-sided polygon is called an "icosagon" If it is a regular icosagon - all its sides and angles are equal - then it's interior angles are all 162 degrees. You can verify this by drawing a line to the centre from each angle.. There will be 20 small angles arranged in a circle around the centre. These must total 360 degrees. As 360 / 20 = 18, this leaves the other angles of each triangle to add up to 162, because the interior angles of a triangle total 180 degrees.
It will have 2 opposite equal angles of 33 degrees and 2 opposite equal angles of 147 degrees
A 10 sided polygon which is a decagon and its interior angles add up to 1440 degrees.
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 6840 degrees
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 6660 degrees.
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 1620 degrees
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 1980 degrees.
The sum of the interior angles of any polygon of n sides is equal to 180(n - 2) degrees.
If each interior angle is 176 degrees it will have 90 equal sides.
The 3 interior angles of any triangle add up to 180 degrees
The total for the interior angles depends on the number of sides. The formula for the total of interior angles of an n-sided polygon is sum =180(n-2). This is 180 degrees for triangles, 360 degrees for quadrilaterals, and 540 degrees for pentagons.
A square or a rectangle both have 4 equal interior angles of 90 degrees
A polygon with 50 sides, given the sum of all the interior angles in 8640.
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees.
