Question 4.

Take a circular sheet of paper. Fold it into two halves. Press the fold and open it. Do you find the crease of a diameter ? Repeat the same activity by changing the fold. How many diameters do you observe ? How many more diameters can be formed ?

Answer:

Fold a circular sheet of paper into two halves. Press the fold and open it. We find the crease (a line made on paper when it is pressed) of a diameter. We observe infinite number of diameters.
