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.
Not necessarily. Only if the minor arc is less than 1/4 of the circle. If the minor arc is more than 1/4 of the circle, then the central angle is obtuse.
minor arc
Sometimes~ Minor arcs have central angles less than 180 degrees because 180 is a semi-circle and above 180 is a major arc. An acute angle is less than 90 degrees, so this is only true sometimes.
An acute central angle will subtend an acute arc, or one that is less than 1/4 of the whole circle.
No, because there is no acute angle in a circle.
minor arc of cord is half of major arc of same cord
the measure of a minor arc equals the measure of the central angle that intercepts it.

Oh, dude, it's like a piece of cake! So, a minor arc is like a slice of pizza, right? And the central angle is like the angle at the center of the pizza. If the minor arc is 155 degrees, then the central angle is also 155 degrees. Easy peasy, lemon squeezy!
