Geometry: Division of Segments and Angles (Level 1 of 8)

This video tutorial series covers key geometry concepts such as midpoints, bisectors, trisection points, trisectors, adjacent angles, angle bisectors, and angle trisectors. It explains how segments and angles can be divided into congruent parts using these concepts. The video provides examples and diagrams to illustrate these ideas, emphasizing the properties and definitions of each concept. The tutorial concludes with a recap of the main points and a preview of the next video, which will apply these concepts through basic examples.

What is the term for a point that divides a segment into two equal parts?

• Vertex
