Centers of a Triangle

Leo Fogel
This file shows the different centers of a triangle that are made by the intersection of perpendicular bisectors, angle bisectors, medians, and altitudes. It's also color coded! One of the angles of the triangle is dependent on the slider, so you can see how the centers move for different types of triangles. I suggest hiding/unhiding like color lines and points so you can see each case one at a time.
