Using segment addition postulate to find the value of a segment

The video tutorial explains how to find the length of a segment RT using the segment addition postulate. It starts by introducing a line with points RS&T and their respective segment lengths. The segment addition postulate is explained with an example, and then applied to calculate the length of RT. The tutorial concludes with a summary and an invitation for questions.

Explain the segment addition postulate in your own words.

What does the equation Rs + St = RT represent in geometry?

If Rs is 15 and St is 9, how would you calculate RT?

What is the value of segment RT based on the given segments Rs and St?

Describe a real-life scenario where the segment addition postulate could be applied.
