Angles In Parallel Lines

The video tutorial explains the properties of parallel lines and various types of angles formed by them, such as alternate, corresponding, interior, and vertically opposite angles. It highlights key angle facts, including 180 degrees on a straight line and 360 degrees around a point, and provides exercises to apply these concepts. The video concludes with a puzzle to reinforce learning.
