...FG ; but, by hypothesis, BC : EF : : AC : DF ; consequently FG = DF ; hence the triangles EGF, DEF, **have the three sides of the one equal to the three sides of the other, each to each** ; they are therefore equal (43). But, by construction, the triangle EGF is equiangular with the triangle... | |
