depends what polygon because a decagon is 144 degrees
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.
Interior Angles: n-2 (n is number of sides) ____ 180 Exterior angles are always 360 degrees.
180*2
You cannot calculate interior angles in a polygon. You can only calculate their sum. The sum of all the interior angles of an n-sided polygon is (n-2)*180 degrees. So for example, the interior angles of a triangle (n = 3) sum to 180 degrees. But the individual angles can be (1,1,178), or (30,60,90) or infinitely many other combinations.
Regular polygons with interior angles of 150 degrees are dodecagons (12-sided polygons). The formula for the interior angle of a regular polygon is ((n-2) \times 180^\circ / n), where (n) is the number of sides. Setting this equal to 150 degrees and solving for (n) confirms that only the dodecagon meets this criterion. Thus, the only regular polygon with interior angles of 150 degrees is the regular dodecagon.
180 degrees
Polygons do not normally have interior angles of 180 degrees or more.
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.
Interior Angles: n-2 (n is number of sides) ____ 180 Exterior angles are always 360 degrees.
A concave polygon is a polygon with at least one interior angle greater than 180 degrees. This causes the polygon to have at least one "dent" or indentation in its shape. The presence of these interior angles greater than 180 degrees distinguishes concave polygons from convex polygons, which have all interior angles less than 180 degrees.
It will have (7200+360)/180 = 42 sides
180 degrees, for all 3-sided polygons and triangles
By definition a regular polygon cannot be concave. Concave polygons contain one or more interior angles that are greater than 180 degrees, and regular polygons can never have an interior degree greater than 180 degrees.
The sum of the interior angles of a triangle is 180 degrees. This is because one angle of a triangle is 60 degrees.
All polygons have an interior angle sum of 180(n-2) degrees where n is the number of sides. 180(9-2)=180*7=1260 degrees

You cannot calculate interior angles in a polygon. You can only calculate their sum. The sum of all the interior angles of an n-sided polygon is (n-2)*180 degrees.
