Equation of a perpendicular line

In geometry, finding the equation of a perpendicular line is useful when working with shapes like squares and rectangles or analyzing graphs. Perpendicular lines meet at a right angle (90 degrees), and their slopes are opposite reciprocals. This concept helps in tasks such as determining how to build structures with perfect corners or understanding angles in real-world designs like roads and bridges. Jump to the questions
