ellipse

IPA（発音記号）

/ɪˈlɪps/

名詞

(geometry) A closed curve, the locus of a point such that the sum of the distances from that point to two other fixed points (called the foci of the ellipse) is constant; equivalently, the conic section that is the intersection of a cone with a plane that does not intersect the base of the cone.

日本語の意味

幾何学における楕円。2つの焦点からの距離の和が一定である点の軌跡をなす閉曲線。

The mathematician traced an ellipse on the paper to illustrate how the sum of distances to the foci remains constant.

数学者は、その性質を示すために、焦点からの距離の和が一定である点の軌跡である楕円を紙に描いた。
