Once you understand midpoint, You can solve

This video tutorial explains how to use the midpoint of a line segment to solve for missing lengths and variables. It covers setting up algebraic equations based on midpoint properties, solving for variables, and calculating line segment lengths. The video concludes with a brief introduction to the next topic.

What is the significance of knowing that R is the midpoint of line segment PQ?

• It means RQ is shorter than PR.

• It means PQ is longer than PR.

• It means PR and RQ are equal in length.

• It means PR and RQ are different in length.

How do you start solving for X in the equation involving PR and RQ?

• By setting the expressions equal to each other.

• By subtracting one expression from the other.

• By adding both expressions together.

• By multiplying both expressions.

What is the value of X when the equation is solved?

• 1

• 2

• 3

• 1/2

How do you find the length of PR once you have the value of X?

• By substituting X into the expression for PR.

• By dividing the expression for PR by X.

• By adding X to the expression for RQ.

• By multiplying X by the expression for PR.

What is the total length of PQ if PR and RQ are both 11/2?

• 22/2

• 22

• 11/2

• 11
