Video Summary

When a piece of paper with shapes is folded over a central thick line, some shapes on the left side align perfectly with shapes on the right side. To fit, they must be equal distances from the center and flipped along their axis. An arrow, two triangles, and an arrow fit perfectly, but a circle and two triangles do not due to distance and orientation issues. Therefore, three shapes fit when the paper is folded: one arrow and two triangles. The solution is C3, which indicates three matching shapes.
