A square card printed with the letter N is held horizontally, as shown in the diagram, where the arrow indicates the direction of North. The card is turned over by rotating it through 180° about an axis running from East to West, and then turned over by rotating it through 180° about an axis running from North-East to South-West.
How does the diagram on the card now look to a person facing North?
