Understanding Angles and Lines

The video tutorial covers the fourth-grade math concept of lines and line segments, focusing on understanding and identifying parallel and perpendicular lines. It explains the characteristics of parallel lines, which never intersect, and perpendicular lines, which intersect at right angles. The tutorial uses examples and visual aids to help students differentiate between these types of lines and solve related problems.
