Skew lines — In geometry, skew lines are two lines that do not intersect but are not parallel. Equivalently, they are lines that are not both in the same plane. A simple example of a pair of skew lines is the pair of lines through opposite edges of a regular… … Wikipedia
Zцllner lines — an optical illusion in which long parallel lines seem to converge or diverge owing to their being crossed by a series of short lines parallel to one another but oblique to the long lines and at reverse oblique angles to both adjacent series of… … Medical dictionary
Tangent lines to circles — In Euclidean plane geometry, tangent lines to circles form the subject of several theorems, and play an important role in many geometrical constructions and proofs. Since the tangent line to a circle at a point P is perpendicular to the radius to … Wikipedia
