1、perpendicular distance
2、We will denote by h the perpendicular distance from p to the inclined face.
3、Chordal deviation is the perpendicular distance between the actual curve and the approximating line segments.
4、The product of a quantity and its perpendicular distance from a reference point.
5、the perpendicular distance from the base of a geometric figure to opposite vertex (or side if parallel).
6、The perpendicular distance from the base of a geometric figure to the opposite vertex, parallel side, or parallel surface.
7、This method not only keep the curve through the critical points but also with the shortest perpendicular distance, thus restore the critical points.
8、A line considered a limit to a curve in the sense that the perpendicular distance from a moving point on the curve to the line approaches zero as the point moves an infinite distance from the origin.
