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.
Any angle which is less than 90 degrees is an acute angle.

A triangle has three angles. The sum of these 3 angles = 180°. At least two of the 3 angles will be acute angles (less than 90°). The third angle can be acute, or a right angle (equal to 90°) or obtuse (between 90° and 180°). Triangles can be categorized by the angles (acute, right or obtuse).
An acute angle is under 90 degrees, an obtuse angle is over 90 degrees.
As the angle is between 90 degrees and 180 degrees it is an obtuse angle.
by measuring the angle and if it is below 90 degrees it is acute if it is higher than 90 degrees its obtuse
1 acute angle = 1 acute angle
An angle below 90 degrees is know as an acute angle.
acute
That is an acute angle. An obtuse angle is not acute.
An acute angle
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.
