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.

Explain how to determine the sum of the lengths of segments PQ and QR.

Describe the geometric relation that must hold true for the lengths of segments NA, AX, and NX.

What does it mean for points A, E, R, and S to be non-collinear?
