ACTIVITY – BASIC GEOMETRICAL IDEAS
Objective:
Forming angles through paper folding
Materials Required:
Paper, Pencil and a sheet of white paper.
Procedure:
Take a sheet of paper.
2. Fold the sheet of paper equally on the half.
3. Unfold the paper. After unfolding it, two 90 ° angles are marked on the crease of the paper.

4. Now, fold again one side of 90 ° angle in a triangular shape (see figure).
Two 45 ° angles will be formed which is half of 90 °.
5. Take another sheet of paper. Fold it twice to make three equal parts.

6. Now, unfold the paper and count the number of angles formed.
Measure each of the angles.
On unfolding two 30 °angles are formed.
8. By folding again one of the two 30 ° angles on half, we can create two new angles of 15° each.
