In mathematics, perpendicular lines intersect at a right angle, while skew lines are lines that never intersect and exist in different planes. Understanding these types of lines is fundamental in geometry. An example of perpendicular lines is the axes on a graph, while an example of skew lines would be the edges of a cube. ;
The two correct terms are perpendicular lines and skew lines. Perpendicular lines intersect at a right angle, while skew lines do not intersect and are in different planes. This distinction is essential in geometry.
