Understanding Angles and Lines

This video tutorial from Math Antics introduces the concept of angles in geometry. It begins with a discussion on lines, including parallel and intersecting lines, and how they form angles. The video explains how to name angles using points and symbols, and describes different types of angles such as right, acute, obtuse, and straight angles. It also covers complementary and supplementary angles, providing a comprehensive overview of these fundamental geometry concepts.

What do we call lines that never meet, no matter how far they are extended?
