Identifying Points, Lines, and Rays

This video tutorial teaches how to identify geometric figures such as points, rays, lines, and line segments by observing their characteristics. It explains how shapes are classified based on their sides and provides real-world examples of geometric figures. The tutorial covers the definitions and labeling of points, lines, line segments, and rays, and addresses common misunderstandings in geometry.
