Properties of Lines and Angles

The video tutorial explains the concepts of parallel, intersecting, and perpendicular lines. It describes how intersecting lines form angles, and how parallel lines remain equidistant and never intersect. Perpendicular lines intersect to form right angles. The video provides examples and models to identify these lines and offers instructions on drawing them. It concludes with a call to action for viewers to like and subscribe.

What is the defining characteristic of intersecting lines?
