What are Perpendicular Lines?

Perpendicular lines are lines that intersect each other at a 90° angle i.e., forming right angles where they meet.

In other words, if two lines are perpendicular, they meet or cross each other in such a way that each angle formed at the intersection is a right angle.

Perpendicular means two lines or surfaces that meet at a right angle, forming an “L” shape. In simpler terms, it’s like when two lines cross each other to make a perfect corner, like the edges of a square. Perpendicular lines are crucial in geometry and everyday life, as seen in structures like buildings, furniture, and road markings.

Examples of Perpendicular Lines

Perpendicular lines are two straight lines that meet at a 90° angle i.e., forming an “L” shape. Here are some everyday examples:

• The corners of a square are connected by perpendicular lines.
• The walls of a room often meet at right angles, forming perpendicular lines.
• The edges of a bookshelf, where the shelves meet the sides can form perpendicular lines.
• A crosswalk on the road often consists of two perpendicular lines.
• The corners of a piece of paper or a rectangular table form perpendicular lines.

Perpendicular means two lines or surfaces that meet at a right angle, forming an “L” shape. They go in different directions and intersect at a 90-degree angle. This article explains what perpendicular lines are, gives examples, and shows their importance in everyday life, including construction, navigation, and geometry, in easy-to-understand language.
