An equilateral triangle can be subdivided into 2 and into 4 congruent pieces. Divide it into 3 congruent pieces.

Is it possible to divide it in to 5 congruent pieces? 6? 7?

I love sharing stuff I made and love when people share stuff that they made. And, even more, I love when people take the ideas of others and remix them. In this case, @MathButler was inspired by something I did to create his own version. I think he streamlined what I did along the way.
