How many degrees a regular polygon measures depends on how many sides it has. For example, a pentagon measures 540 degrees. A triangle measures 180 degrees. To calculate a pentagon for example, use this formula. A pentagon has 5 sides. Take away 2 which is 3. Then multiply it by 180 to get your answer.
A regular polygon will have 360 sides with exterior angles of 181 degrees.
15 equal sides

If it is a regular polygon then it will have 360/12 equals 30 sides

5 sides and it is a regular pentagon
A regular polygon will have 360 sides with exterior angles of 181 degrees.
A regular polygon cannot have an interior angle that is less than 60 degrees.
15 equal sides

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.
A regular polygon that has 180 degrees is an equilateral triangle.
The sum of the exterior angles of any irregular or regular polygon is 360 degrees. In this case it is a regular polygon. 360/60 = 6 sides It is a regular hexagon that has 6 equal sides.
