How many sides does a regular polygon have if the measure of an angle is 12?
The smallest internal angle possible for a regular polygon is 60 degrees. So either the angle is not 12 degrees or it is not an internal angle.

What is the measure of one angle of a regular convex 20-gon?
A triangle has an internal angle of 180/3 A square has an internal angle of 360/4 A pentagon has an internal angle of 540/5 An 'x'-agon has an internal angle (180(x-2))/x = (180x-360)/x = 180 - 360/x A 20-agon has an internal angle of 180 - 360/20 = 162

What name is given to the angle where total internal reflection occurs?
Total internal reflection occurs when the angle of incidence with respect to the normal at the boundary to a less dense medium exceeds the critical angle.
