Sažetak
In the papers [2], [3] using the facts from the conics theory in the Euclidean,
pseudo-Euclidean and quasi-hyperbolic planes, we have studied and proved numerous facts related to Steiner’s deltoid in various ways. In this paper, the intention
is to see what can be said about the curves of the center in some special pencil of
conics and to show how, studying the center curves in the special pencil of conics a
connection with Steiner’s deltoid curve has been found.
