A segment bisector
It would be False because a secant is a line or segment that passes through a circle in two places.
It is diameter.
The segment that passes through a vertex and is perpendicular to the opposite side is called the altitude of the triangle.
perpendicular
side
Altitude.
A median of a triangle is a line or segment that passes through a vertex and bisects the side of the triangle opposite the vertex.
A median of a triangle is a line or segment that passes through a vertex and the midpoint of the side opposite that vertex. The median only bisects the vertex angle from which it is drawn when it is an isosceles triangle.

No, the perpendicular bisector of a side of a triangle does not necessarily pass through the opposite vertex. The perpendicular bisector is a line that is perpendicular to a segment at its midpoint, and it may intersect the interior or exterior of the triangle, depending on its shape. In fact, the only time a perpendicular bisector passes through the opposite vertex is in the case of an isosceles triangle, where the two sides are equal, and their perpendicular bisectors coincide with the altitude.
Not necessarily. That only happens in isosceles and equilateral triangles.
Go get a math book and look it up, stop being lazy.
A segment bisector
The major segment.
