Yes, since a+b=90, a and b being the two angles, and an acute angle is less than ninety, it is impossible for an angle to be greater or equal to ninety. Thats why.

1 acute angle = 1 acute angle
No.If an angle is acute, it is less than 90 degrees.Its complement is the number of degrees needed to total 90.Its supplement is the number if degrees needed to total 180, which is 90 more than its complement.
An acute angle is an angle less than 90°. So an angle of 17° is an acute angle.
Acute angle = <90 degrees Right angle = 90 degrees Obtuse angle = >90 degrees To answer your question, obtuse angle is larger.
yes. to be and acute angle, all angles must be acute. Obtuse angles only one angle has to be obtuse. Right angles only need one too. Acute has to have every angle to be acute, if one angle is obtuse or right, it's automatically no an acute Angle anymore.
