A segment is a part of a line. An arc is a part of a circle.
Arc
circular arc is a segment of the circumference of a circle
The region bounded by an arc and a chord is known as a "segment" of a circle. This segment includes the area enclosed by the chord and the arc connecting the endpoints of the chord. The segment can vary in size depending on the length of the chord and the curvature of the arc. If the chord is a diameter, the segment is known as a semicircle.
arc
an arc is a segment of a circle. If the arc subtends a full angle of 360 degrees, then the arc is a circle; but this is a special case of an arc.
The segment is called a secant.The area bounded by a secant and its arc is a sector.

An arc is an unspecified segment of a circle. I perferred the second segment of the presentation.
Take a compass, extend it about 3/4 of the length of the segment. Then from one end of the segment, draw a 180 degree arc. From the other end draw another arc. Connect the points where the arcs intersect. Where the line intersects with the segment is the midpoint of the segment. That is how you bisect a segment to find the midpoint - geometrically.
Adjust a compass so the distance between the point and the pencil is more than half of the length of the segment. With the point at one end of the segment draw an arc that intersects the segment. Without adjusting the compass, with the point at the other end of the segment draw an arc that intersects the first arc at two places. The line that includes those two intersecting points is the perpendicular bisector.
