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.

What are the given lengths of segments RS and ST in the problem?

• RS = 12, ST = 7

• RS = 10, ST = 5

• RS = 15, ST = 9

• RS = 8, ST = 6

According to the Segment Addition Postulate, if AB = 5 and BC = 3, what is the length of AC?

• 7

• 8

• 9

• 10

What does the Segment Addition Postulate state about segments AB and BC?

• AB times BC equals AC

• AB minus BC equals AC

• AB plus BC equals AC

• AB divided by BC equals AC

How is the Segment Addition Postulate applied to find the length of RT?

• By subtracting ST from RS

• By multiplying RS and ST

• By dividing RS by ST

• By adding RS and ST

What is the calculated length of segment RT?

• 22

• 24

• 26

• 20
