An angle that measures less than 90 degrees is an acuteangle.
Note:
Angles less than 90 degrees are called "acute" angles.
An angle that is exactly 90 degrees is called a "right" angle.
Angles that are more than 90 degrees but less than 180 degrees are call "obtuse" angles.
An angle that is exactly 180 degrees is called a "straight line".
Angles that are more than 180 degrees and less than 360 degrees are called "reflex" angles.
is called an acute angle. An obtuse angle measure in degrees is more than 90.

Acute angle
An angle that measures more than 90 degrees but less than 180 degrees is called an "obtuse" angle. Note Angles less than 90 degrees are called "acute" angles. An angle that is exactly 90 degrees is called a "right" angle. Angles that are more than 90 degrees but less than 180 degrees are call "obtuse" angles. An angle that is exactly 180 degrees is called a "straight line". Angles that are more than 180 degrees and less than 360 degrees are called "reflex" angles.
It is an obtuse angle because it is greater than 90 but less than 180 degrees
This is usually called a reflex angle.
An angle from 181 degrees to 359 degrees is called a reflex angle. A reflex angle is an angle that measures greater than 180 degrees but less than 360 degrees. It is formed by rotating a ray less than one full revolution, resulting in an angle that extends beyond a straight line.
It is an obtuse angle because it is greater than 90 but less than 180 degrees
