Understanding Parallel and Perpendicular Lines

The video tutorial introduces the concept of parallel lines, explaining their properties and how to identify them in geometric shapes like rectangles and squares. It includes exercises to practice identifying parallel and perpendicular lines, emphasizing that parallel lines never intersect. The tutorial also covers the characteristics of perpendicular lines and how to recognize them using tools like a set square.

What happens when you extend the opposite sides of a rectangle?
