Question
Use colour, a thread and a folded paper to draw symmetrical shapes.
Advertisements
Solution
Take any color, a thread, and a folded square paper.
Step 1:
Take a folded square paper which is folded along one of its axis of symmetry.
Step 2:
Open the paper. Draw a square in one comer. Place the thread in the square drawn and apply colour on it as shown in the figure.
Step 3:
Remove the thread. You will see a white patch where the thread was.
Step 4:
Fold the paper and press it along the axis of symmetry. When you unfold the paper, you will see an imprint on the other side of the fold which is identical to the color patch you had made earlier.
