Answer:

PQ = RS

A P Q R S B

<-----x------><------y------><-----x----->

Let's say PQ = RS =x

and QR = y

PR = PQ + OR

PR = x + y

QS = QR+RS

QS = y + x

QS = x + y

QS = PR

PR = QS

Hence PR congruent to QS

Given Question :-

On a line AB, take four point P, Q, R and S in order such that PQ is equal to RS. State whether they are congruent to QS. Give reason in support of your answer.

\large\underline{\sf{Given- }}

P, Q, R and S are four points on AB taken in order such that PQ = RS

\large\underline{\sf{To\:state - }}

Is it true PQ = RS = QS ?

\large\underline{\sf{Solution-}}

As it is given that, P, Q, R and S are the points on AB taken in order and PQ = RS

We know, From Euclid Lemma, part is smaller than the whole.

Now, From given data, we concluded that RS is a part of QS

\rm\implies \:RS &lt; QS

\rm\implies \:RS  \:  \ne \:  QS

\rm\implies \:PQ  \:  \ne \:  QS

So,

\rm\implies \:PQ \:  =  \: RS   \:  \ne \:  QS

Hence, Given statement is not true.
