For any polygon: (number of sides-2)*180 = sum of interior angles
The sum of the interior angles of a convex polygon is 180*(n-2) degrees, where n is the number of vertices and angles.That depends on how, many sides the polygon has.-- Subtract 2 from the number of sides.-- Multiply that number by 180.-- The result is the sum of the interior angles in that polygon.It doesn't matter whether the sides of the polygon are all equal ("regular" polygon), orwhether it's all funny and squashed. You only need to know the number of sides it has.
Subtract the interior angle from 180
4 triangles make 1 hexagon. (easy way to find out how many triangles there are in a polygon- take number of sides of the polygon, subtract 2 from it, that's your answer!)
Yes * * * * * Not true! A circle is a 2-d shape that is not a polygon. A polygon must have sides that are straight lines. A 2-d shape need not have straight sides.
If you multiply 360 by the number of angles in the polygon and then subtract the sum of all the interior angles you will end up with the sum of all the exterior angles of the polygon.
