米克尔-斯坦纳点轨迹

Miquel-Steiner's point locus

Yuriy Zakharyan

摘要:

本文重新表述了Miquel-Steiner定理,并得到了任意三角形的Miquel-Steiner点轨迹。证明了该轨迹与共轭圆和Brocard圆有关。此外,我们还得到了当cevian相互垂直时,当cevian形成相似三角形时的Miquel-Steiner点轨迹.证明了如果Miquel-Steiner点属于直线,则Cevinans交点属于平行于等角的直线。最后,我们得到了一些结果的情况下,当Miquel-Steiner的点与三角形中心重合。

英文摘要:

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.
