No.
Yes. Pentadecagon (15-sided polygon)
Not possible - the smallest interior angle for a regular polygon is 60 degrees - which creates an equilateral triangle.
45 degrees, which would be the interior angle of a equilateral triangle
Not possible in this Universe. Smallest regular polygon is a triangle when interior angles are 60o. If exterior angles are 30o the polygon has 360/30 ie 12 sides.
No.
No.
Most certainly. That regular polygon is an equilateral triangle.
No.
Yes. Pentadecagon (15-sided polygon)
No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more.
No, it's not.

Not possible in this Universe. Smallest regular polygon is a triangle when interior angles are 60o. If exterior angles are 30o the polygon has 360/30 ie 12 sides.
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 interior angles of a regular polygon cannot be less than 60 degrees so 24 degrees is not possible. ------------------------------- However a regular polygon with EXTERIOR angles of 24° has 360° ÷ 24° = 15 sides.
