Segment Addition and Midpoint Concepts

The video tutorial covers segment addition and midpoint concepts. It provides three examples: the first two focus on using the midpoint to find unknown values in segments, while the third example demonstrates segment addition. The tutorial explains how to set up equations based on given information and solve for unknowns, emphasizing the properties of midpoints and segment addition.

What does it mean when M is the midpoint of segment AB?

• M is at the end of segment AB

• M divides AB into two equal parts

• M is outside segment AB

• M is the longest part of segment AB

If M is the midpoint of AB and one side is 36, what is the length of AB?

• 18

• 72

• 54

• 36

In the second example, what is the first step to solve for X?

• Divide both sides by X

• Multiply both sides by X

• Add X to both sides

• Subtract X from both sides

What is the value of X in the second example?

• 3

• 6

• 5

• 4

How do you find the length of segment RS once you have X?

• Multiply X by 2

• Divide X by 2

• Subtract 4 from X

• Add 4 to X

In the third example, what is the total length of segment AC?

• 5

• 3X

• 9

• 14

How do you formulate the equation to find X in the third example?

• AB + BC = AC

• AB - BC = AC

• AB / BC = AC

• AB * BC = AC

What is the value of X in the third example?

• 4

• 2

• 3

• 5

What is the length of segment BC when X is found in the third example?

• 8

• 7

• 6

• 9

How can you verify your answer in the third example?

• By dividing AC by AB

• By multiplying AB and BC

• By subtracting AB from AC

• By adding AB and BC to see if it equals AC
