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.

How can one identify collinear and non-collinear points in a geometric problem?

What is the significance of the statement 'the sum of the lengths of any two sides of a triangle is always greater than the length of the third side'?

What are the common mistakes students make when interpreting angles in diagrams?
