Hugo sent us pictures of his solution. Well done, Hugo!

I know that the area of a triangle is given by the forumula $\frac{1}{2} \times base \times height.$ The original triangle has base $1$ and height $1$, so as long as each triangle on the way also has base $1$ and height $1$ the area will stay the same".
