It's called a Midpoint.
It could be the diameter of a circle that produces 2 congruent segments or the midpoint of a line segment
angle bisector
A line segment that divides a circle in two is a chord.If the two parts of the circle are equal, the line segment is a diameter.See 'The Parts of the Circle' in Sources and related links, below.
