Hint: in a regular polygon interior plus exterior = 180o, always.
How many sides does a regular polygon have if each exterior angle measures 20?
540 degrees
180
The shape is a triangle.
360 degrees and the polygon is an equilateral triangle.
36
Hint: in a regular polygon interior plus exterior = 180o, always.
The exterior angles of any polygon add up to 360.
How many sides does a regular polygon have if each exterior angle measures 20?
If exterior angles are 120 then interior angles must be 60 so you have an equilateral triangle
The exterior angles add up to 360 degrees
The sum of a regular polygons exterior angles always = 360
360
The exterior angles of any polygon add up to 360 degrees.
The exterior angles of any polygon add up to 360.
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
