Perpendicular Lines

The video tutorial explains the concept of perpendicular lines, focusing on their properties and how they intersect at 90-degree angles. It covers the equation of straight line graphs, the concept of reciprocals, and how these relate to perpendicular lines. The tutorial also demonstrates how to identify perpendicular lines by comparing gradients and solving related problems using coordinate points and equations.
