Objective: Find the centre of a circle by folding paper.
Materials Required: A paper sheet, a pencil, a pair of scissors, a circular object (a bangle,
a plate, or a bowl, etc.)
Procedure:
Trace the circle on a paper sheet with the help of a
circular object and cut it out.
Fold the circle into two equal parts.
A O B
Now again fold it into halves. The circle is now folded
into four equal parts.
A B O A(B) O
Now, open out the circle.
A O B
Clearly, the two creases formed on the circle intersect
each other at a point. This point O is the centre of the
circle. O
Measure the diameter and radius of the circle formed.
Confirm if the diameter is double the radius.
