The article below draws our attention on the problem that most of the I-st year students don’t know the theorem of three perpendiculars and its reciprocals. We consider that the deficient assimilation of this very theorem has as a main reason its lame methodological exposition in the school manuals of mathematics. Here are formulated 7 reciprocal forms of the theorem of those three perpendiculars establishing which of them is a theorem. |
