If you have 10 pennies in a triangle, move 3 pennies to make the triangle point in the opposite direction.
Why don't you try this with ten pennies?
To solve this task, you can imagine the arrangement of the 10 pennies in a triangle. Then, follow these steps to move 3 pennies and make the triangle point in the opposite direction:
1. Visualize the original triangle formed by the 10 pennies. Ensure that you have a clear understanding of its orientation.
2. Select three pennies that are part of one side of the triangle. It's important to choose three adjacent pennies to maintain the triangle shape.
3. Carefully lift these three pennies together as a group, while keeping their relative positions unchanged.
4. Rotate the group of three pennies 180 degrees, so that they reverse their orientation.
5. Place the group of three pennies back in the original position, with their reversed orientation.
By following these steps, you will successfully move 3 pennies to make the triangle point in the opposite direction.
