Labeling Figures in Geometry

This video tutorial covers the basics of labeling and naming geometric figures, including points, lines, line segments, rays, and planes. It explains how to identify and represent these figures using capital and lowercase letters, arrows, and other notations. The tutorial also discusses angles, triangles, and the concepts of collinearity and perpendicularity, providing examples and explanations to help students understand these geometric principles.
