What is the size of an interior angle of a 20 sided regular polygon?
exterior angle = 360° ÷ 20 sides = 18° interior angle = 180° - exterior angle = 180° - 18° = 162°

How many sides does a regular polygon have with the angle 20 degrees?
If those are exterior angles, the exterior angles of any polygon add up to 360. That would be 18 sides.
What is a 18 sided 3D shape called?

Interior angle for 20 sided shape?
Exterior angle = 360/20=18 interior angle = 180 - 18 = 162 Must be regular shape
What is the exterior angle of an 20 sided shape?
If it's regular then 360/20 = 18 degrees
What shape has a exterior angle of 20 degrees?
A regular 18 sided polygon has 18 exterior angles each measuring 20 degrees
Interior angle of and 18 sided shape?
Exterior angle + interior angle = 180 Hence Interior Angle = 180 - Exterior Angle The Exterior Angle = n(No. of sides ) / 360 Substituting Interior Angle = 180 - (n/360) Interior Angle = 180 - (18/360) Interior Angle = 180 - (1/20) Interior Angle = 179.95 degrees.
