The 8 interior angles add up to 1080 degrees
360 ________________________________________________ Sum of Interior Angles of a Polygon = 180 (n-2) Sum of Exterior Angles of a Polygon = 360 The sum of an angle and an exterior angle of a regular polygon is 360
Interior Angle: 150 degrees (Interior Angle Sum: 1800) Exterior Angle: 30 degrees (Exterior Angle Sum: 360)
The exterior angle sum is 360 degrees. It doesn't matter whether the polygon is regular or not, and it doesn't even matter how many sides it has.
180
For any polygon, regular or otherwise, the sum of exterior angles is always 3600.
Octagons are eight-sidedThey can have a maximum of 4 pairs of parallel linesEach interior angle is 135 degrees.The sum of its interior angles are 1080 degrees
360 ________________________________________________ Sum of Interior Angles of a Polygon = 180 (n-2) Sum of Exterior Angles of a Polygon = 360 The sum of an angle and an exterior angle of a regular polygon is 360
Interior Angle: 150 degrees (Interior Angle Sum: 1800) Exterior Angle: 30 degrees (Exterior Angle Sum: 360)
The sum of the five interior angles of ANY pentagon is 540 degrees.If the pentagon is regular, then each angle is 108 degrees.
There is no regular polygon with an interior angle of 20o. If the interior angle is 120o then there are six sides and the sum of the angles is 720o.
The exterior angle sum is 360 degrees. It doesn't matter whether the polygon is regular or not, and it doesn't even matter how many sides it has.

For a regular polygon with sides n, the sum of the interior angles = (n-2)180Therefore, a regular polygon has interior angle sum equal to 540o.(5-2)180=(3)180=540
