Acute, obtuse, and right are varieties of, for ten points, what three-sided geometrical figure?
One important point in this figure can be found by taking the isotomic conjugate of the Gergonne point; that point is the Nagel point. The Euler line connects the center of the nine-point circle, the (*) circumcenter, the orthocenter, and the centroid, and this figure's angles always add up to 180 degrees.
