座標平面上で2つの数の座標で各点を一意に指定するシステム

a system that specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular directed lines, measured in the same unit of length

one of the coordinates in a system of coordinates that locates a point on a plane or in space by its distance from two lines or three planes respectively; the two lines or the intersections of the three planes are the coordinate axes

平面上または空間内の点をそれぞれ2本の直線または3枚の平面からの距離によって位置づける座標系における座標の1つ。2本の直線または3枚の平面の交点は座標軸とされる。
