The Barycenter is one of the triangle's notable point. It indicates the center of mass of an object.

It is the crossing point of the three medians of the triangle.

You can move the figure below to see what happens to the barycenter when you move around A, B and C.




:
Bisector is a line that passes exactly "in the middle" of two points.

Bisector is a region whose points are equidistant (same distance) to two points.

In the drawing we see that points A and B have a bisector. Move the points and see what happens with the bisector.
