It was given the detailed solution of a number of original problems formulated by B.P. Fedorov a spell ago. These problems flow organically from the study of the nontrivial properties of Euclidean triangles, including its poorly understood properties, provided with Lemoine point and Brocard point.
Key words: triangle properties, division of the sections, Lemoine point, Brocard point, Van Obel theorem.
