How to Use the Segment Addition Postulate to Find Unknown Lengths

Miacademy & MiaPrep Learning Channel

This educational video provides a clear and practical introduction to the Segment Addition Postulate in geometry. It begins by conceptually exploring the relationship between points, demonstrating that for the lengths of two smaller segments to equal the length of the total segment, the points must be collinear. This visual approach helps distinguish the postulate from the Triangle Inequality Theorem before formally defining the mathematical rule.
