Question

Divide the line segment $RS=10.25cm$ in two equal parts.

Answer 1

1. Draw a line segment RS = 10.25 cm.

2. With any radius greater than 5.17 cm, 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 (PQ) is the perpendicular bisector of RS.

Hence, RO and SO are two equal parts.
