If $AB = 7.5\ cm$ and $CD = 2.5\ cm$, construct a segment whose length is equal to:
$AB - CD$
$AB - CD$

Answer
Given: $AB= 7.5\ cm$ and $CD = 2.5\ cm$ Draw $AB$ and $CD$
Now, take a divider and open it such that ends of both the arms are at $A$ and $B$. Then, we lift the divider and place its one end at $E$ and other end $(F)$ and on the line I as shown in figure. Now, reset the divider in such a way that the end of its one hand is at $C$ and the end of the other hand is at $D$. Then, we lift the divider and place its one end at $E$ and other end ( $G$ ) on the line I as shown in the figure. $F G$ is required line segment, whose length is equal to ( $A B-C D$ )
