geometry – Triangular geometric construction from 2 medians and from one side

So here's the problem: using only a ruler and a compass, geometrically build a triangle from the three given segments representing the base (side $ c $) and the medians of the other two sides ($ m_ {a} $ and $ m_ {b} $).

The 3 given segments

I've looked at many websites that were trying to get help for this build, but I found only two-sided triangles and a median or two medians builds and an altitude. I know I'm supposed to start with the side $ c $ and draw circles using the medians, but that's about it all. How can I do this?
