The video tutorial explains the concept of perpendicular lines, highlighting that they intersect at 90 degrees. It describes how to verify perpendicularity by checking if the product of their gradients equals -1. The tutorial includes examples to illustrate this concept and demonstrates how to find the gradient of a perpendicular line using the formula m2 = -1/m1. It also touches on finding the equation of a perpendicular line when given a point it passes through.
