If all of the interior angles of the polygon add up to 180 degrees,
then the polygon is a triangle.
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. 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. 1980 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 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
A square or a rectangle both have 4 equal interior angles of 90 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 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.
