Question

Draw any right-angled triangle and construct its circumcircle.

Answer 1

1. Draw a base $AB$ of any length. Take ${90}^{\circ }$ from point $A$ and mark any point $C$ on it. Join $B-C$. $△BAC$ is a right-angled triangle.

2. Draw perpendicular bisectors of $AB$ and $AC$ and let them intersect at $O$.

3. With centre as $O$ and radius as $OB$, draw the circumcircle of $△BAC$.
