Angles greater than 90 but less than 180 degrees are obtuse angles Angles greater than 180 but less than 360 degrees are reflex angles
Obtuse angles are greater than 90 degrees but less than 180 degrees. Straight angles are exactly 180 degrees. Reflex angles are greater that 180 degrees.
Angles are measured in degrees, minutes and seconds Acute angles are greater than 0 but less than 90 degrees Right angles are 90 degrees Obtuse angles are greater than 90 but less than 180 degrees Reflex angles are greater than 180 but less than 360 degrees A full rotation is 360 degrees
They are as follows:- Acute angles are greater than 0 but less than 90 degrees Right angles are 90 degrees Obtuse angles are greater than 90 but less than 180 degrees Reflex angles are greater than 180 but less than 360 degrees A full rotation is 360 degrees
Greater than 0 degrees but less than 90 degrees.
