Question
Using a set square and a ruler, test whether $l \| m$ in the following cases:
✓
Answer
Place the ruler so that one of its measuring edges lies along the line $l.$Hold it firmly with one hand.
Now place a set square with one arm of the right angle coinciding with the edge of the ruler.
Draw line segments between $l$ and $m$ (say $PM, RS, AB$) with the set square.
Now, we see that $PM = AB = RS$.
Thus, we can say that $l \| m.$

$HCF$ of co-prime numbers $4$ and $15$ was found as follows:
$4 = 2$ $\times$ $2$ and $15 = 3$ $\times$ $5$
since there is no common factor, so $H.C.F.$ of $4$ and $15$ is $0$. Is the answer correct? If not, what is the correct $H.C.F$.
