...construction, AG is equal to DE ; hence AH is equal to D F. Therefore the two triangles AGH, DEF, having two **sides and the included angle of the one equal to two...and the included angle of the other, each to each,** are themselves equal (Prop. V. Bk. I.). But the triangle AGH is similar to ABC ; therefore DEF is also... | |
