Concept #17: Summary of Points of Concurrency Angle Bisectors Perpendicular Bisectors Medians Name of point of concurrency Special Notes: Special Triangles: (inside, outside, somewhere else? – be specific) Equilateral Obtuse Right 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? Altitudes Altitudes Medians Perpendicular Bisectors Angle Bisectors Equilateral Triangles Obtuse Triangles Right Triangles
