...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... | |

...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... | |
