Question

With $\overline{PQ}$ of length $6.1cm$ as diameter, draw a circle.

Answer 1

A perpendicular bisector of a line segment is a line segment perpendicular to and passing through the midpoint of the line segment.

Steps of construction:
(i) Draw a line segment $\overline{PQ}$ of length $6.1cm$.
(ii) Draw the perpendicular bisector of PQ which cuts, it at O. Thus O is the mid-point of $\overline{PQ}$.
(iii) Taking O as centre and OP or OQ as radius, draw a circle where the diameter is the line segment $\overline{PQ}$

Hence, we get the figure as below:.
