... corresponding angles were congruent, but corresponding sides were proportional, but could be different size triangles. For congruent triangles, corresponding sides have to be congruent. Knowing all angles are congruent, is not enough to prove triangles are congruent. ...

Apollonian network
In combinatorial mathematics, an Apollonian network is an undirected graph formed by a process of recursively subdividing a triangle into three smaller triangles. Apollonian networks may equivalently be defined as the planar 3-trees, the maximal planar chordal graphs, the uniquely 4-colorable planar graphs, and the graphs of stacked polytopes. They are named after Apollonius of Perga, who studied a related circle-packing construction.
