It's AMAZING that these 9 points form a circle.
What happens when we have form and isosceles and equilateral triangle?
It is so difficult for three lines to intersect making the centroid, orthocenter and circumcenter very special points. It turns out these three points are allowed COLLINEAR, which is amazing! There is also a distance relationship between these three points. Cool stuff.
Here's a review of Medians, Altitudes, Angle Bisectors and Perpendicular Bisectors along with a review of the special points: Centroid, Orthocenter, Incenter and the Circumcenter.
