Each interior angle is 165 degrees
Each exterior angle is 15 degrees
An interior or exterior angle of the polygon.
The sum of the exterior angles of any regular polygon is 360°
A polygon is a closed figure in the plane. It has an inside and an outside.The angles on the inside are the interior angles. An exterior angle is the angle between any side of the polygon and a line extended from the next side.Here is an example to help.If you draw an triangle, the angles inside it are interior angles. Then if you extend any side, the angle between that line and the next side is the exterior angle.The sum of the exteriors is always 360. For a polygon with n sides, the sum of the interior angles is 180 (n-2) degrees.
An exterior angle of a polygon is the supplement of the corresponding interior angle. The exterior angle is the angle between an extended sides of the polygon and the next side of the polygon.
24 degrees providing that it is a regular polygon. (And since each interior angle is 156 deg, it IS a regular 15-gon.) 360/15 = 24 degrees
An interior angle of 128 implies an exterior angle of 180-128 = 52 degrees. If so, the regular polygon has 360/52 sides ie 6.9 sides. A fractional side is not possible.
The exterior angle of any polygon, including a tricontakaitrigon, is the angle formed between one side of the polygon and the extension of an adjacent side. The measure of the exterior angle of a regular tricontakaitrigon is 2 degrees, as each interior angle of this polygon measures 178 degrees.
The smallest regular polygon, an equilateral triangle, has interior angles of 60. A square has interior angles of 90. There can't exist a regular polygon with interior angles of 30.

The number of sides of a regular polygon is 360 divided by the size of the exterior angle. The external angle is 180 - the internal angle. So for a regular polygon with an internal angle of 135 we get the following. 360 / (180 - 135) = 360 / 45 = 8 sides
If the polygon is regular, the measure of one interior angle of a 24 side polygon is 165 degrees.
400 exterior angle = 360/9 = 400
