Circumcenter where the 3 perpendicular
bisectors cross Is the center of a circle that
goes around the outside of a triangle and touches
only the vertices

Incenter where the 3 angle bisectors cross Is
the center of a circle that goes inside a
triangle and touches the sides of the triangle at
only one point

Centroid the balance point where the 3 medians
of the triangle cross A median goes from the
midpoint of one side to the vertex opposite

Orthocenter where the 3 altitudes of the
triangle cross An altitude is measured
perpendicular to a side and going to the vertex
across

For a right triangle the circumcenter is always
on the hypotenuse and the orthocenter is always
at the 90º angle. For all triangles the incenter
and centroid are always inside the triangle
