Concept #17: Summary of Points of Concurrency Angle Bisectors Perpendicular Bisectors Altitudes Medians Name of point of concurrency Special Notes: (Donâ€™t include Euler line here) Special Triangles: (inside, outside, somewhere else?) Obtuse ! Right ! Equilateral ! Euler Line 1. Which points are always on the Euler Line? 2. What Is unique about the Euler line in an : Isosceles Triangle? 3. Which points are always the endpoints? 4. Which point is always the center? 5. When the ! is not equilateral or isosceles, what do you notice about the way the Euler line is divided? (measure the segments) Equilateral Triangle?
