Question

Divide the line segment $AB=7.5cm$ into two equal parts.

Answer 1

Step 1: Draw a line $AB$ of length $7.5cm$ using a ruler.

Step 2: Place the compass on point $A$ and draw two arcs above and below line $AB$ with radius greater than $3.75cm$

Step 3. Repeat the above step by placing a compass on $B$ such that the arcs from point $B$ intersect the arcs from point $A$.

Step 4: Join the intersection points of the arcs and let it intersect line$AB$ at $C$.

Thus, $C$ divides line $AB$ in the ratio $1:1$, i.e, two equal parts.
