Orthocenter, Circumcenter, and Centroid calculator. No incenter because I'm too dumb.
- Orthocenter - intersection of all three altitudes
- Altitude - line that passes through one vertex of the triangle and is perpendicular to the opposite side
- Circumcenter - intersection of all three perpendicular bisectors of the triangle sides
- Centroid - intersection of all three medians
- Median - line that passes through one vertex of the triangle and the midpoint of the opposite side
