Identifying Parallel & Perpendicular Lines In 2 Dimensional Figures

This video tutorial explains the concepts of intersecting, perpendicular, and parallel lines in two-dimensional figures. It describes how intersecting lines meet at a point, perpendicular lines form right angles, and parallel lines never intersect, maintaining a constant distance. The tutorial uses figures to demonstrate these properties, showing how to identify and verify them through examples. By the end, viewers will understand how to recognize these line types and their characteristics in geometric figures.

Describe the relationship between lines AD and BC in the second figure.
