Question

Draw an equilateral $\Delta ABC$ with side $6.4cm$ and construct its circumcircle.

Answer 1

Steps of Construction :
(i) Construct an equilateral $\Delta ABC$ with $AB=BC=CA=6.4$ $cm$.
(ii) Draw the perpendicular bisectors of sides $AB$ and $BC.$ Let $O$ be their point of intersection.
(iii) Draw a circle with centre $O$ and radius $OA$. Thus, the circle so obtained is the required circumcircle of $\Delta ABC$.
