No, a segment is not necessarily perpendicular. A segment is simply a straight line connecting two points. A perpendicular segment would be a segment that forms a right angle with another segment or line.
It is an altitude.
A segment.
you cant awnser that question its not possible * * * * * The answer is a MEDIAN.
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 line segment connecting two vertices of a polygon is called an edge if the vertices are adjacent to one another. Otherwise it is called a diagonal.
line segment
In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposing side.
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.
That would be a vertex.

a right angle
