Minor arc
87 degrees
The interior angle and central angle are supplementary, that is they always add up to 180 degrees, while the exterior angle and the central angle will always be the same.
obtuse
90 degrees and 180 degrees
An angle that measures 210 degrees is a reflex angle.
An angle that measures between 0 and 90 degrees is an acute angle.
87 degrees
The interior angle and central angle are supplementary, that is they always add up to 180 degrees, while the exterior angle and the central angle will always be the same.
An angle of between 90 degrees and 180 degrees is called an obtuse angle, an angle that is exactly 180 degrees is called a straight angle (because it creates a straight line), and an angle of more then 180 degrees is called a reflex angle.
An obtuse angle
180 degrees is a straight line
Between 15 and 20 degrees...
A right angle (90 degrees)
That is an obtuse angle.
An obtuse angle
How about 6 degrees?
