ABC and DEF are two triangles, DEF being the greater, which are so located that each pair of corresponding sides are parallel. From A, C two perpendiculars AG, CH are drawn to DF, from B, C another two perpen- diculars BK, CL are drawn to EF, and from A, B a third pair of perpendicu- lars AM, BN are drawn to DE. Show that AK² +BH² + CM² = AL² + BG² + CN². From A, B, C draw AP'P, QBQ', CR'R s to each pair of opposite parallel sides of the As
