Question

A line segment $RS$ of $4.75cm$ is given. Divide the line segment in two equal parts.

Answer 1

1. Draw a line segment $RS=4.75cm$.

2. With any radius greater than $2.37cm$, and compass fixed at $R$, draw $2$ arcs, one above and one below $RS$.

3. With the same radius, compass at $S$, cut the $2$ arcs drawn in step $2$.

4. The line joining these two arcs $\left(PQ\right)$ is the perpendicular bisector of $RS$.

Hence, $RO$ and $SO$ are two equal parts.
