There are as many interior and exterior angles as there are sides (the line segments that make up the polygon. The sum of each pair of exterior angle and interior angle is 180 degrees, i.e. they are supplementary. For concave polygons, there will be at least one "negative" exterior angle paired with an interior angle of greater than 180 degrees - the total of the angles is still 180 degrees.

How many interior angles does a many sided polygon have?
(number of sides -2)*180 = sum of interior angles
What is a polygon with all interior angles congruent?
A polygon with all interior angles congruent Is known as a regular polygon.
How many sides does a polygon have if the interior angles equal 1260?
Sum of interior angles of a polygon = (2n - 4)right angles 1260 = (2n - 4) x 90 1260 = 180n - 360 900 = 180n n = 5, it is a pentagon
If the sum of the interior angles of a polygon is 900 how many sides does the polygon have?

How many sides does a regular polygon have if its interior angles are all 15 degrees?
The interior angles of a regular polygon must be 60 degrees or greater.
