A parallel of a curve is the envelope of a family of congruent circles centered on the curve. It generalises the concept of parallel (straight) lines. It can also be defined as a curve whose points are at a constant normal distance from a given curve. [1] .
Parallel curves are curves that do not touch each other or intersect and keep a fixed minimum distance. In three-dimensional Euclidean space, a line and a plane that do not share a point are also said to be parallel. However, two noncoplanar lines are called skew lines.
May 19, 2021 · Parallel curves in a given plane may appear identical but are actually not superimposable and thus are not congruent. Translational shifted functions in a plane are not parallel curves because the shortest perpendicular distance between them is not constant along the curves.
Sep 5, 2021 · Through a point not on a given line one and only one line can be drawn parallel to the given line. So in Figure \(\PageIndex{3}\), there is exactly one line that can be drawn through \(C\) that is parallel to \(\overleftarrow{\mathrm{AB}}\).
Even though parallel transported lines intersect on the sphere, there is a feeling of local “parallelness” about them. In most applications of parallel lines, the issue is not whether the lines ever intersect, but whether a transversal intersects them at congruent angles at certain points; that is, whether the lines are parallel
Parallel lines do not meet each other at any point, in a plane. They are always at an equidistant apart. When a transversal cuts parallel lines, a pair of angles are formed. Learn properties and examples at BYJU’S.
