What are Perpendicular Lines?
A perpendicular lines in mathematics, are the two lines that intersect each other at a 90° angle. At point of intersection perpendicular lines forms four right angles.
Perpendicular lines are represented with symbol “⊥” i.e., AB ⊥ CD means line segment AD is perpendicular to line segment CD. Some examples of perpendicular lines include the sides of a square, the axes of a coordinate plane (x-axis and y-axis), or the legs of a right triangle.
Perpendicular Line Definition
Two lines are referred to as perpendicular when they cross one another at a 90° angle.
Parallel and Perpendicular Lines
Parallel and Perpendicular Lines are two sides of one coin. Perpendicular lines are intersecting lines, whereas parallel lines never intersect. Parallel lines in geometry are lines that never intersect and are always at the same distance from each other. On the other hand, perpendicular lines are lines that intersect each other at a right angle, forming a 90° angle. In this article, we will discuss these in detail, including examples and differences.
