In the center of a square pie, there is a raisin. From the pie, you can cut off a triangular piece along a line that intersects two adjacent sides at points other than the vertices; from the remaining part of the pie - the next piece (in the same way) and so on. Can you cut out the raisin?

In the solution to problem 79618, it is proven that a raisin can be cut out if and only if it can be cut out with one cut. Therefore, a raisin located at the center of a square cake cannot be cut out.

## Answer

cannot.
