...that is, A c : A b : : 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...about the equal angles proportionals, the triangles** are equiangular, and consequently similar ; we have seen that the two triangles A bc, A!' F"E" are... | |
