Obtuse angle
Types of angles according to measure: 1. Acute angle- angle measure is less than 90 degrees 2. Right angle- angle measure is 90 degrees 3. Obtuse angle- angle measure is more than 90 degrees but less than 180 degrees. 4. Straight angle- angle measure is 180 degrees 5. Reflex angle- angle measure is more than 180 degrees but less than 360 degrees
116 degrees
The measure of an acute angle is anything less than 90 degrees, or a right angle.
Acute angle
Acute
An acute angle.
The angle with measure more than 0 degrees and less than 90 degrees is an acute angle, the angle with measure 90 degrees is a right angle,the angle with measure more than 90 degrees and less than 180 degrees is an obtuse angle and the angle with measure 180 degrees is a straight angle. Finally, an angle of more than 180 degrees and less than 360 degrees is a reflex angle.
An angle whose measure greater than 90 but less than 180 is an obtuse angle.
An acute angle
That's an 'acute' angle.
