Description

Perpendicular lines are lines that intersect at a right angle (90 degrees). This concept is fundamental in geometry and is used to define and construct various geometric shapes. For example, the sides of a square are perpendicular to each other. Understanding perpendicular lines is crucial for solving problems related to angles, shapes, and coordinate geometry.
