Can you fold the square sheet in such a way so as to get a shape with 4 sides? How many corners does it have now?
Yes, we can fold the square sheet to get a shape with 4 sides.
Method: Fold the square in half by joining opposite edges (not corners).
Result: We get a smaller rectangle.
Properties: It has 4 sides and 4 corners.
Conclusion: ∴ A square folded this way remains a quadrilateral with 4 corners.
Explanation
The chapter encourages exploration through paper folding. When a square is folded by bringing opposite edges together (not corners), it creates a rectangle with 4 sides and 4 corners. This helps children understand that folding can create different shapes while maintaining some properties.
Solution Steps
Fold the square in half by joining opposite edges (not corners).
Observe that the resulting shape is a smaller rectangle.
Verify that the shape has 4 sides and 4 corners.
