Question

Points​ P, Q,​ R, and S are collinear. Point Q is between P and​ R, R is between Q and​ S, and PQ is approximently = to RS . If PS is 21 and PR​ is 18, what is the value of​ QR?

Answer 1

The value of QR for the given line will be 15 units.

What is a line segment?

A line section that can connect two places is referred to as a segment.

The line is here! It extends endlessly in both directions and has no beginning or conclusion.

In other terms, a line segment is merely a section of a larger, straight line that extends indefinitely in both directions.

Given,

PQ = RS

PR = 18

PS = 21

Now,

RS = PS - PR

RS = 21 - 18 = 3

So,

PQ = 3

Now,

QR = PR - PQ

QR = 18 - 3

QR = 15

Hence the value of QR will be 15 units.
