Given the centroid, one vertex, and the angles of a triangle, how do you solve it?

Assuming you know the angles of a triangle, but the only piece of information regarding scale that you're given is the coordinate of the centroid and coordinate of a single vertex (whose corresponding angle is known), is it possible to solve the triangle? If so, how does one go about doing so?

You could construct an arbitrary triangle with the given angles, construct its centroid and then use a similarity to map your initial triangle to the final one. The solution will be unique if you know the orientation of the triangle, otherwise you get two mirror copies.
