What is the Perpendicular Line Theorem?

perpendicular  In geometry, two geometric objects are perpendicular if their intersection forms right angles at the point of intersection called a foot  perpendicular Adj perpendicular Adj

The perpendicular line equation can be derived from the equation of a line that is written in the form y = m x + b We studied, that the slopes of perpendicular · erect · on end · plumb Strong matches straight · upright Weak match vertical

Key Takeaways · Parallel lines have the same slope · Perpendicular lines have slopes that are opposite reciprocals In other words, if m=ab, Revision notes on Parallel & Perpendicular Lines for the Edexcel IGCSE Maths syllabus, written by the Maths experts at Save My Exams
