A 3-sided polygon is called a "triangle".
The angles of a triangle don't equal 180 degrees.
They total 180 degrees when they're added.
A 10 sided polygon which is a decagon and its interior angles add up to 1440 degrees.
A three-sided polygon is a triangle. The angles in a triangle add up to 180 degrees.
The sum of the exterior angles of a polygon, however many sides it has, is 360 degrees. If the 20 sided polygon is regular, its angles are equal, and each is then 360/20 = 18 degrees.
Exterior angles add up to 360 degrees Interior angles add up to 1260 degrees
For any n-sided regular polygon, the sum of the internal angles of the polygon is equal to (n - 2) x 180. In this instance, the sum of the internal angles of a 14-sided shape is equal to (14 - 2) x 180 = 2160 degrees.
A 10 sided polygon which is a decagon and its interior angles add up to 1440 degrees.
A three-sided polygon is a triangle. The angles in a triangle add up to 180 degrees.
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 166.153846 repeating degrees
The sum of the exterior angles of a polygon, however many sides it has, is 360 degrees. If the 20 sided polygon is regular, its angles are equal, and each is then 360/20 = 18 degrees.
The sum of the interior angles of a four-sided polygon is 360 degrees.
Exterior angles add up to 360 degrees Interior angles add up to 1260 degrees
The angles of a 8 sided Polygon is 45 degrees.
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 1620 degrees
For any n-sided regular polygon, the sum of the internal angles of the polygon is equal to (n - 2) x 180. In this instance, the sum of the internal angles of a 14-sided shape is equal to (14 - 2) x 180 = 2160 degrees.
The interior angles of a fifteen sided polygon amount to 2340 degrees.
The interior angles of a 17 sided polygon add up to 2700 degrees
If the 12-sided polygon is 'regular', then each of its exterior angles is 30 degrees. Whether the polygon is regular or not, all 12 of its exterior angles still add up to 360 degrees, but they may not all be equal.
