360 degrees.
If each angle measures 90 degrees the polygon is a square and so its angles sum to 360 degrees.
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.
The sum of the interior angles is 360 Degrees or 2 Pi Radians.
In a triangle, the sum of the measures of the angles is 180 degrees.
The sum of the measures of the interior angles of a heptagon is 900 degrees.
SUPPLEMENTARY ANGLES are two angles the sum of whose measures is 180 degrees.
Two angles are complementary if the sum of their measures is 90 degrees.Two angles are supplementary if the sum of their measures is 180 degrees.
Two angles are complementary if the sum of their measures is 90 degrees.Two angles are supplementary if the sum of their measures is 180 degrees.
find the sum of the measures of the interior angles of 13-gon.
The sum of the measures of the exterior angles of an octagon (and any polygon) is 360o.
Triangle, since the sum of its angles is 180. The sum of the angles of the square, rectangle, and rhombus are all 360.
4: Think of a square, 4 angles each 90o
