...consequently, the two equiangular triangles BAC, CED, are similar figures. Cor. Two triangles which **have two angles of the one equal to two angles of the other,** are similar ; for, the third angles are then equal, and the two triangles are equian gular (BI, p.... | |

...the angle EBC (4): and the angle AEG is equal to the angle BEH (a); therefore the triangles AEG, BEH **have two angles of the one, equal to two angles of the other, each to each,** and the sides AE, EB, adjacent to the equal angles, equal to one another; wherefore they have their... | |

...and the right angle BED (I. Ax. 11) to the right angle BF D. Therefore the two triangles EBD and FBD **have two angles of the one equal to two angles of the other, each to each** ; and the side BD, which is opposite to one of the equal angles in each, is common to both. Therefore... | |
