Four-Corner Method

Imagine you have four cards, each with a different picture on them. You want to put them in a square shape so they all fit together nicely. The four-corner method is a way to make sure the cards are evenly spaced and form a proper square shape.

Here's how you can use the four-corner method:

1. Start by placing one card in the top left corner of where you want your square to be. This will be your first corner.

2. Next, take another card and place it in the top right corner. This will be your second corner.

3. Now, take a third card and place it in the bottom left corner. This will be your third corner.

4. Finally, take your fourth card and place it in the bottom right corner. This will be your fourth corner.

If done correctly, the cards should form a perfect square with equal spacing between each card. This method can be used for other shapes as well, such as triangles or circles, by adjusting the placement of the cards to fit the desired shape.
