How to calculate Perpendicular distance between a point and a line The perpendicular distance (d) of a line Ax + By+ C = 0 from a point (x1 ,y1) is given by d = | Ax1 + by1 + c|/ root (A^2 + B^2) complete explanation of formula and solved example. 1  Education. 2  Standard YouTube License.
Two lines that intersect and form right angles are called perpendicular lines. The symbol â¥ is used to denote perpendicular lines. In Figure , line l â¥ line m. Figure 2 Perpendicular lines. Two lines, both in the same plane, that never intersect are called parallel lines. Parallel lines remain the same distance apart at all times. The symbol // is used to denote parallel lines. In Figure 3, l // m. Figure 3 Parallel lines.
