It is called a bisector.
The middle of a line segment is called a Midpoint.;-)
the midpoint
A point on a segment that is halfway between the two endpoints is called the midpoint of the segment. It is the point that divides the segment into two equal parts.
A bisector.
It is called a bisector.
Such a line is called a perpendicular bisector.
A line segment that intersects with or joins two points on a circle is called a chord.

the midpoint
It's called a perpendicular bisector of the line segment.
midpoint
A point on a segment that is halfway between the two endpoints is called the midpoint of the segment. It is the point that divides the segment into two equal parts.
if that line segment intersects the centre of the circle it is called a radius.
A bisector.
I believe this is called the perpendicular bisector.
Assuming that you meant midpoint, it is a median.
