  In this paper we reformulate Miquel-Steiner's theorem and we obtain
Miquel-Steiner's point locus for an arbitrary triangle. We prove that this
locus is related to conjugate circles and Brocard's circle. In addition, we
obtain Miquel-Steiner's point locus in a case when cevians are perpendicular to
each other, in a case when cevians form similar triangles. In addition, we
prove that if Miquel-Steiner's point belongs to line, then cevinans
intersection point belongs to line which is parallel to isogonal. Finally, we
obtain few result for cases when Miquel-Steiner's point coincides with triangle
centres.
