Question

Euler line in Right angled triangle, Isosceles triangle and Equilateral triangle

Answer 1

Step-by-step explanation:

Euler showed in 1765 that in any triangle, the orthocenter, circumcenter and centroid are collinear. In equilateral triangles, these four points coincide, but in any other triangle they are all distinct from each other, and the Euler line is determined by any two of them.
