Each interior angle measures 60 degrees and they add up to 180 degrees
It is in fact an equilateral triangle

Hint: in a regular polygon interior plus exterior = 180o, always.
360 degrees and the polygon is an equilateral triangle.
How many sides does a regular polygon have if each exterior angle measures 20?
The sum of the measures of the exterior angles of any polygon, regular or irregular, is always 360 degrees. In a regular polygon with ten sides, each exterior angle measures 360 degrees divided by the number of sides, which in this case is 36 degrees. Therefore, the sum of the measures of the exterior angles of a regular decagon is 10 multiplied by 36 degrees, which equals 360 degrees.
The sum of the exterior angles of a regular polygon = 360° If an exterior angle measures 8° then the number of sides = 360/8 = 45
