Not necessarily. It can be obtuse. It cannot, however, be a reflex angle.

Minor arc
In a circle, a central angle is formed by two radii. By definition, the measure of the intercepted arc is equal to the central angle.
Central angle
An arc can be measured either in degree or in unit length. An arc is a portion of the circumference of the circle which is determined by the size of its corresponding central angle. We create a proportion that compares the arc to the whole circle first in degree measure and then in unit length. (measure of central angle/360 degrees) = (arc length/circumference) arc length = (measure of central angle/360 degrees)(circumference) But, maybe the angle that determines the arc in your problem is not a central angle. In such a case, find the arc measure in degree, and then write the proportion to find the arc length.
