...let the side DE of the triangle DE be equal to 8. Then as the three angles of the one triangle are equal to the three angles of the other, each to each, and AB and DE are opposite equal angles, the remaining sides of each triangle will bear the same proportion... ## The Texas Mathematics Teachers' Bulletin, Volumes 1-7

...translation. There is, however, one case presenting a striking difference. On S, if two triangles have three angles of the one equal to the three angles of the other, the triangles are either symmetric or congruent; in P they are merely similar. Corresponding to these... ## Proceedings of the Edinburgh Mathematical Society, Volume 2
