Draw an equilateral ΔABC with side 6.2 cm and construct its circumcircle
उत्तर
Steps of construction:
1. Construct the equilateral ΔXYZ of side equal to 6.2 cm.
2. Draw the perpendicular bisectors PR and QS of sides `bar(XY)` and `bar(YZ)` respectively.
3. Mark the point of intersection as O.
4. Draw a circle with centre O and radius OX or OY or OZ.
This is the required circumcircle.
