What is the name of an angle above 270 but less than 360?
An angle above 270 but less than 360 degrees is called a reflex angle.
What is it called when an angle goes past 360 degrees?
There is not a special name. You simply use the name for the angle which is left after you subtract 360 degrees from the angle.
Why is the angle in the center of a polygon always a multiple of nine?
Because if you measure the angle in degrees, it is always 360 degrees. And 360 happens to be a multiple of 9. However, to students of advanced mathematics, the angle at the centre would always be 2*pi radians which is not a multiple of 9.
What would be the central angle of a 12 sided polygon?
Any angle between 0 and 360 degrees.Any angle between 0 and 360 degrees.Any angle between 0 and 360 degrees.Any angle between 0 and 360 degrees.
What is the exterior angle the interior angle and the angle at the center of a regular polygon with 15 sides?
Exterior angle = 360/number of sides = 360/15 = 24 degrees.Interior angle = 180 - Exterior angle = 180 - 24 = 156 degrees.Angle at centre = Exterior angle = 24 degrees.Exterior angle = 360/number of sides = 360/15 = 24 degrees.Interior angle = 180 - Exterior angle = 180 - 24 = 156 degrees.Angle at centre = Exterior angle = 24 degrees.Exterior angle = 360/number of sides = 360/15 = 24 degrees.Interior angle = 180 - Exterior angle = 180 - 24 = 156 degrees.Angle at centre = Exterior angle = 24 degrees.Exterior angle = 360/number of sides = 360/15 = 24 degrees.Interior angle = 180 - Exterior angle = 180 - 24 = 156 degrees.Angle at centre = Exterior angle = 24 degrees.
