...: A b, that is, A c : A 6 : : A" E": A" F". Now it is demonstrated in treatises on geometry,* that **if two triangles have one angle of the one equal to one angle of the other, and the sides about** the equal angles proportionals, the triangles are equiangular, and consequently similar ; we have seen... | |
