One of many constructions of the tangent and point of tangents to ellipse is considered. The correctness of the presented constructions is proved by means Pascal’s theor
Using the classic construction of a parabola’s tangent some properties of a conics streak and pencil are proved. These properties as a theorem in a more general case were published in the paper [1].The possibility of utilizing the theorem to construct the tangents and points of tangency to ellipse defined by the conjugated diameters and to hyperbola defined by its asymptotes is shown.
