Yes.
Bisect a segment is to divide the line segment into 2
No
equidistant from the endpoints of a segment -odewah chin chin
No. Since a line is infinite, it has no mid-point. A bisector must go through a midpoint so nothing can bisect a line (not even a segment).
No
The symbol for bisect is typically represented by a line segment with a point in the middle, indicating that it divides the segment into two equal parts. In mathematical notation, the term "bisect" may also be denoted using the symbol "∠" for angles, or simply by stating that a segment or angle is bisected. For example, if line segment AB is bisected at point C, it can be expressed as AC = CB.
If your question was: Does a midpoint bisect a segment? Then yes it does... It divides it in half.
Measure it or bisect it with a compass
Yes. it is possible to bisect a segment with a perpendicular segment. Follow the link to learn how to do it: http://www.mathopenref.com/constbisectline.html
To find its mid point. Which then raises the question why find its midpoint and I cannot answer that.
No
False that is to find the perpendicular bisect.
