The largest exterior angle measure is 120o. It is the exterior measure of an equilateral triangle (which is a regular polygon).
360/number of sides = exterior angle
If it's a regular polygon then each exterior angle measures 36 degrees
Providing that it's a regular polygon then each exterior angle will measure 12 degrees.
With a protractor or if you know the exterior angle then it's 180 - exterior angle = interior angle
It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line
Providing that it is a regular polygon then each exterior angle will measure 12 degrees
The measure of the exterior angle of a 11-sided polygon = 360⁰/11 = 32 72/99⁰ = 32 8/11⁰
Providing that it is a regular 12 sided polygon then each exterior angle measures 30 degrees
360/number of sides = each exterior angle
400 exterior angle = 360/9 = 400
