Answer 1

$\:\:\:\huge\color{pink}\boxed{\colorbox{black}{AnSwEr}}$

Procedure

Step 1: Construct a parallelogram ABCD on the sheet of white paper.

Step 2: Draw the diagonal AC of the parallelogram.

Step 3: Make an exact copy of ΔABC on the glazed paper. Label it as ΔA’B’C’. Cut ΔA’B’C formed on the glazed paper.

Step 4: Rotate ΔA’B’C’ formed on the glazed paper and place it over the ΔACD

Step 5: Remove ΔA’B’C’. In the parallelogram ABCD draw the other diagonal BD.

Step 6: Mark the point O where the diagonals AC and BD intersect.

Step 7: Fold the paper along the line passing through the point O such that the line OA falls over the line OC as shown in Figure 21.2. Record your observations (see Observation 2).

Step 8: Fold the paper along the line passing through the point O such that the line OB falls over the line OD.
