Geometry: Collinearity, Betweenness, and Assumptions (Level 2 of 4)

The video covers five examples illustrating collinearity and betweenness of points. It starts with drawing and measuring a shaded segment on a number line, followed by determining which point is between two others using segment lengths. The third example involves finding possible coordinates of a point between two others. The fourth example requires drawing a diagram based on collinear point relations, and the final example involves creating a diagram with intersecting line segments for non-collinear points.
