Hi, can any triangle be divided into isosceles triangles? How to prove or disprove that? Thanks a lot.
LoL, I think I got it.
You can always inscribe a circle in a triangle. Then, connecting the points of tangency with the sides of the triangle to the center of the circle and drawing another triangle whose vertices are also those tangency points, we obtain six isosceles triangles within the original one.
Don't you guys think so?
