Geometry: Collinearity, Betweenness, and Assumptions (Level 1 of 4)

This video tutorial covers key geometry concepts including collinearity, betweenness of points, triangle inequality, and assumptions from diagrams. It explains how to identify collinear and non-collinear points, the conditions for a point to be between two others, and the triangle inequality theorem. The video also provides guidance on interpreting diagrams, emphasizing what assumptions can and cannot be made.
