Question

Construct the circumcircle of equilateral $\Delta PQR$ with side $6.3cm$.

Answer 1

1. Draw base $QR$ of length $6.3cm$. Mark arcs of length $6.3cm$ from points $Q$ and $R$ and mark the intersection point as $P$.

2. Join $P-Q$ and $P-R$. $△PQR$ is the required triangle.

3. Draw perpendicular bisectors of $PQ$ and $QR$ and let them intersect at $O$.

4. With $O$ as the centre and $OQ$ as the radius, construct the circumcircle of $△PQR$.
