 centroid the point of concurrency of the medians of a triangle circumcenter the point where the three perpendicular bisectors of the sides of a triangle meet circumcircle a circle that passes through all three vertices of a triangle equilateral triangle a triangle with three equal sides incenter the point of concurrency of the three angle bisectors of a triangle incircle the circle inscribed in a triangle medial triangle the triangle formed by joining the midpoints of the sides of a triangle nine point circle this circle has its center at the midpoint of the segment joining the orthocenter and the circumcenter.  Its radius is half of the circumradius of the triangle.  The nine points are the 3 midpoints of the sides of the triangle, the feet of the 3 altitudes of the triangle, and the midpoints of the segments joining the vertices and the orthocenter. orthic triangle the triangle formed by joining the feet of the altitudes of a triangle orthocenter the point where the three altitudes of a triangle intersect pedal triangle the triangle formed by selecting a point in the plane, constructing perpendicular lines from that point to the three sides of the triangle, and connecting the feet of those perpendicular lines.
