Special Notes:
(Don’t
include Euler

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)
