(number of sides - 2)*180 = total sum of interior angles
The sum of the interior angles of a polygon with n sides is 180*(n-2) degrees.
A 29-sided polygon.
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
It depends on what type of polygon it is and how many angles it has.
(number of sides - 2)*180 = total sum of interior angles
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 sum of the interior angles of a polygon with n sides is 180*(n-2) degrees.
A 29-sided polygon.
A pentagon
No
The sum of each pair of interior and exterior angles of a polygon is always 180 degrees.
Im stuck on that too :/
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
sum of internal angles = 180(n-2) where n is the total number of sides of the polygon.
(number of sides-2)*180 = total sum of interior angles
The method of finding the sum of the interior angles of a polygon is by multiplying the (number of sides)-2 by 180, so the sum of the interior angle measures in a 25-sided polygon would be 23*180, or 4140 degrees.
