Professor L.Steingarts has launched several hypotheses that some specially constructed points of a triangle belong to one quadratic curve. Some of these hypotheses are denied and some are proven in the paper.
Keywords: Shteingart hypothesis of an ellipse connected with conic triangle, barycentric coordinates, special cases.
