What is an altitude bisector?

Question

I can't find it anywhere online, please answer clearly.

Answer 1

An altitude is a segment that goes from one vertex of a triangle  to the opposite side so that the line segment is perpendicular to the side.  And a bisector cuts something in half.  

Answer 2

Well a bisector is the mid-point of two points.

y2 - y1

----------

x2 - x1

For example...

Points... (3, 5) and (2, 3)

3 - 5 = -2

-------

2 - 3 = -1

The mid-point is then (-2, -1)
