Sum of interior angles =(no. of sides - 2)180
=(55-2)180
=9540 degrees
The sum of the interior angles add up to 7200 degrees
Im stuck on that too :/
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.
Sum of interior angles of a 38 sided polygon: (38-2)*180 = 6480 degrees
The interior angle of a dodecagon is not 1260 that is of a nonagon * * * * * The interior angle of a dodecagon can have any value in the range (0, 360). The only restriction is that the sum of all 12 interior angles (which need not be equal) is 1800 degrees.
360
Interior Angle: 150 degrees (Interior Angle Sum: 1800) Exterior Angle: 30 degrees (Exterior Angle Sum: 360)
An interior angle is the inside angle of a shape e.g quadrilateral, square
No. An interior angle is one of many angles in the interior of a closed shape - usually a polygon. The angle sum is the sum of the values of a specified list of angles. They may be angles around a point, angles in one or more shapes.
the Sum of the Interior of a triangle is 180
The sum is always 360 degrees. Note, though, that when the interior angle is convex, the measure of the exterior angle is negative.The sum is always 360 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.
360
(number of sides -2)*180 = sum of interior angles
No. It is equal to the sum of the opposite interior angles.
Each interior angle is 120o making the total 720o.
