Answer:
0 is not an acute angle.
Step-by-step explanation:
If the measurement of an angle is between 0 and 90 degrees then we called it an acute angle. It means acute angle is greater than 0 and less than 90 degrees.
Mathematically, we have
0° < Acute angle < 90°
Among all the given options, the angle 89, 45 and 10 is in between 0 and 90 degrees. Hence, these are acute angle.
Thus, 0 is not an acute angle.
