Understanding Perpendicular Lines | A Fundamentally Important Concept in Geometry with Real-World Applications

Perpendicular

Perpendicular refers to the relationship between two lines or segments that intersect each other at a 90-degree angle (also known as a right angle)

Perpendicular refers to the relationship between two lines or segments that intersect each other at a 90-degree angle (also known as a right angle). When two lines are perpendicular, their slopes are negative reciprocals of each other. In other words, if the slope of one line is “m,” then the slope of the other line is -1/m.

Furthermore, perpendicularity can also be observed in the context of segments or rays. Segments or rays are perpendicular when they intersect at a right angle.

Perpendicular lines are commonly represented by the symbol “⊥”. For example, line AB ⊥ line CD indicates that line AB is perpendicular to line CD.

It is important to note that perpendicularity is a fundamental concept in geometry and has various applications in real-world scenarios. It is frequently used in architectural design, construction, and engineering, where precise right angles are required.
