It is impossible for a polygon to have only a measure of 60 degrees...if you mean per angle, then it has to be an equilateral triangle...of course we are talking about regular polygons here, right? :)
well if its 120 degrees it must have 3 sides
15 equal sides
12 sides
If it is a regular polygon then it will have 360/12 equals 30 sides
6
5 sides and it is a regular pentagon
If each interior angle is 175 degrees then the polygon will have 72 sides
It will have 11 sides
It will have 30 sides.
50 sides.
360/36 = 10 sides
13 of them.
