Aim By paper folding verify the result "Diameter is the longest chord of a circle"
Material Required Coloured Paper, pair of scissors, fevistick, ruler , sketch pen
Step 1. Draw a circle of any radius on a coloured paper and cut it.
Step 2. Fold the circle cut out in any way , a crease is formed.
Step 3. On the crease draw a chord AB.
Step 4. Similarly get another chord CD.
Step 5. To get the diameter of the circle, fold the circle in such a way that the crease passes through the centre of the circle. Label the diameter as PQ.
Step 6. Measure the lengths of AB,CD and PQ.
Step 7. Write the observations.
Result On comparing the length of diameter and other chords, it is observed that diameter is the longest chord.
