Verified Answer :

Answer:  \(\overline{MN}\) and  \(\overline{QR}\)


Step-by-step explanation:

Given: In ΔMNO and ΔQRS

\(\frac{SQ}{OM}=\frac{SR}{ON}=4\)

To prove that the triangles are similar by the SSS similarity theorem  [corresponding sides of similar triangles are proportional], there must be the third pair of corresponding sides,

That must be \(\overline{MN}\) and  \(\overline{QR}\)

such that \(\frac{QR}{MN}=4\)



The other sides are \(\;MN{\text{ and }}QR\) that satisfies the SSS similarity theorem.


Further explanation:


SSS similarity theorem states that the three sides of one triangle is proportional to the corresponding sides of the another triangle.


Step by step explanation:


Step 1:


From the given figure it can be observed that the corresponding sides are written below.

\(\begin{aligned}ON \to SR \hfill\\OM \to QS \hfill\\MN \to QR \hfill\\\end{aligned}\)


Step 2:


The length of \(ON\) is 8 units and the length of \(SR\) is 32 units.


Therefore, the ratio of \(SR\) and \(ON\) can be expressed as,

\(\begin{aligned}\frac{{SR}}{{ON}} &= \frac{{32}}{8}\\\frac{{SR}}{{ON}}&= 4\\\end{aligned}\)


Step 3:


The length of \(OM\) is 15 units and the length of \(SQ\) is 60 units.


Therefore, the ratio of \(OM\) and \(SQ\) can be expressed as,

\(\begin{aligned}\frac{{SQ}}{{OM}}&= \frac{{60}}{{15}}\\\frac{{SQ}}{{OM}}&= 4\\\end{aligned}\)


Step 4:


The length of \(MN\) is 15 units and the length of \(QR\) is 60 units.


Therefore, the ratio of \(MN\) and \(QR\) can be expressed as,

\(\begin{aligned}\frac{{QR}}{{MN}}&= \frac{{48}}{{12}}\\\frac{{QR}}{{MN}}&= 4\\\end{aligned}\)


Step 5:


It can be seen that the ratio of corresponding sides of the triangle are proportional as,

\(\Dfrac{{SR}}{{ON}} =\Dfrac{{SQ}}{{OM}} =\Dfrac{{QR}}{{MN}} =4\)


Therefore, the other sides are \(MN\) and \(QR\) that satisfies the SSS similarity theorem.
