Take a cut-out of a parallelogram, say,
ABCD (Fig 3.29). Let its diagonals and meet at O.
Find the mid point of by a fold, placing C on A. Is the
mid-point same as O?
Does this show that diagonal bisects the diagonal at the point O? Discuss it
with your friends. Repeat the activity to find where the mid point of could lie.
Let its diagonals and meet at O.
The mid point of is at point O.Hence, the
mid-point is same as O.
This show that diagonal bisects the diagonal at the point O.
The mid point of is point O.
