...AC : DF, and, by construction, AG = DE ; therefore AH = DF. The two triangles AGH, DEF, have the two sides and the included angle of the one respectively equal to two sides and the included angle of the other ; they are consequently equal. But the triangle AGH is similar to ABC; therefore DEF is... ## Elements of Geometry, Theoretical and Practical: Including Constructions of ...
