| + | # Draw a circle of any radius on a coloured paper and cut it. |
| + | # Paste the circle cut out on a rectangular sheet of paper. |
| + | # By paper folding get chords AB, BC, CD and DA in order. |
| + | # Draw AB, BC, CD & DA. A cyclic quadrilateral ABCD is obtained. |
| + | # Make a replica of cyclic quadrilateral ABCD using carbon paper. |
| + | # Cut the replica into 4 parts such that each part contains one angle . |
| + | # Draw a straight line on a paper. |
| + | # Place angle BAD and angle BCD adjacent to each other on the straight line.Write the observation. |
| + | # Place angle ABC and angle ADC adjacent to each other on the straight line . Write the observation. |
