Question

For drawing the perpendicular bisector of $PQ$, which of the following radii can be taken to draw arcs from $P$ and $Q$?

• A. $\frac{PQ}{2}$
• B. $\frac{PQ}{3}$
• C. $\frac{2PQ}{3}$
• D. $\frac{PQ}{4}$

Answer 1

The correct option is C $\frac{2PQ}{3}$

To draw a perpendicular bisector of a given side, take any length that is greater than half the length of the side. Draw the arcs from the edges of the base. The point where arcs meet is on the perpendicular bisector.

From the given options,

$\frac{2PQ}{3}$ can be considered to draw to draw arcs from edges $P,Q$

Remaining options has the value $\le \frac{PQ}{2}$
