An acute angle is one that is smaller than a right angle, so it covers the range of 0o< (angle) <90o.
1 acute angle = 1 acute angle
That is an acute angle. An obtuse angle is not acute.
An acute angle
An angle is acut if the internal measurement (the smallest one) is less then, but not equal to, 90 degrees. If the angle is 90 degrees, it is a right angle. If it is greater then 90 degrees, it is obtuse.
acute angle
An acute angle is an angle less than 90°. So an angle of 17° is an acute angle.
An acute angle has one angle.
This is an acute angle.
Acute angle = <90 degrees Right angle = 90 degrees Obtuse angle = >90 degrees To answer your question, obtuse angle is larger.
A complement of an acute angle must be an acute angle. An acute angle is an angle whose measure is more than 0 degrees but less than 90 degrees. For example, even if the angle was the minimum 1 degree, the complement is still 89 degrees, which is still acute. Therefore, any combination of a complement of an acute angle MUST be acute.
An angle less than 90 degrees is an acute angle.
