For two lines not in the same plane, see Skew lines#Distance.'' The distance between two straight lines in the plane is the minimum distance between any two points lying on the lines. In case of intersecting lines, the distance between them is zero, because the minimum distance between them is zero (at the point of intersection); whereas in case of two parallel lines, it is the perpendicular distance from a point on one line to the other line. == Formula and proof == Because the lines are parallel, the perpendicular distance between them is a constant, so it does not matter which point is chosen to measure the distance. Given the equations of two non-vertical parallel lines :$y\; =\; mx+b\_1\backslash ,$ :$y\; =\; mx+b\_2\backslash ,,$ the distance between the two lines is the distance between the two intercepts of these lines with the perpendicular line :$y\; =\; -x/m\; \backslash ,\; ,$ This distance can be found by first solving the linear systems :$\backslash begin$ y = mx+b_1 \\ y = -x/m \, , \end and :$\backslash begin$ y = mx+b_2 \\ y = -x/m \, , \end to get the coordinates of the intercept points. The solutions to the linear systems are the points :$\backslash left(\; x\_1,y\_1\; \backslash right)\backslash \; =\; \backslash left(\; \backslash frac,\backslash frac\; \backslash right)\backslash ,\; ,$ and :$\backslash left(\; x\_2,y\_2\; \backslash right)\backslash \; =\; \backslash left(\; \backslash frac,\backslash frac\; \backslash right)\backslash ,\; .$ The distance between the points is :$d\; =\; \backslash sqrt\backslash right)^2\; +\; \backslash left(\backslash frac\backslash right)^2\}\backslash ,,$ which reduces to :$d\; =\; \backslash frac\{\backslash sqrt\; \{a^2+b^2\}\}.$ 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Distance between two straight lines」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
