The interior angles of a triangle must lie within the range (0, 180) degrees. For all other polygons, the interior angles must be in the range (0, 360) excluding 180 degrees.
It is: 180-exterior angle = interior angle
The only regular polygon with an interior angle of 90 degrees is the square, which has four sides. Other polygons can have an interior angle of 90 degrees, but they would not be regular polygons.
It is a 9 sided nonagon and its 9 interior angles add up to 1260 degrees
A concave polygon will always have an interior angle with a measure that is greater than 180 degrees.
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.

An interior angle and the corresponding exterior angle add up to a straight angle. that is, they are supplementary.
A concave polygon has at least one interior angle greater than 180 degrees. A convex polygon has none of those.
The interior angle and the exterior angle are supplementary. That's why you learned about supplementary angles ... or at least they were presented in class ... before polygons.

For regular polygons, the interior angle must be a factor of 360 degrees.Irregular triangles and quadrilaterals (whose angle sums are factors of 360 degrees) will tessellate. For other polygons, I am not aware of any simple rule.For regular polygons, the interior angle must be a factor of 360 degrees.Irregular triangles and quadrilaterals (whose angle sums are factors of 360 degrees) will tessellate.
