How to Identify Vertices, Edges & Faces in Three Dimensional Figures

The video tutorial explains how to identify vertices, edges, and faces in three-dimensional figures, using a rectangular prism as an example. It defines edges as line segments where two faces meet, vertices as points where edges meet, and faces as flat surfaces. The tutorial includes an activity with a pentagonal pyramid to practice identifying these elements. The video concludes with a summary of the concepts covered.
