Angle Bisectors
|
Incenter
Equidistant from sides Center of inscribed (inside) circle |
The angle bisector cuts the vertex angle in half.
|
|
Medians
|
Centroid
Center of balance |
The median goes from a vertex to the midpoint of the opposite side
|
|
Segment (Side) Bisectors
|
Circumcenter
Equidistant from vertices Center of circumscribed (outside) circle |
The segment bisector bisects and is perpendicular to a side.
|
|
Altitudes
|
Orthocenter
Not really useful |
The altitude goes from a vertex to line of opposite side -forming a right angle.
|
|
