Master How to use the segment additon postulate to find the missing length of a line

The video tutorial explains the segment addition postulate, which states that if points are collinear, the sum of the distances between two pairs of points equals the distance between the outermost points. The tutorial begins with basic examples using numbers, then progresses to solving problems with variables and expressions. It concludes with real-world applications, demonstrating how to set up and solve equations using the postulate.
