The figure below shows a compass pointing to the North. In which direction will it point if it turns 90° anti-clockwise?

The compass is initially pointing North.

The compass turns $315^\circ$ anti-clockwise.

A full circle is $360^\circ$. Turning $315^\circ$ anti-clockwise from North means moving through the directions in an anti-clockwise sequence.

• North is $0^\circ$.
• $45^\circ$ anti-clockwise from North is Northwest.
• $90^\circ$ anti-clockwise from North is West.
• $135^\circ$ anti-clockwise from North is Southwest.
• $180^\circ$ anti-clockwise from North is South.
• $225^\circ$ anti-clockwise from North is Southeast.
• $270^\circ$ anti-clockwise from North is East.
• $315^\circ$ anti-clockwise from North is Northeast.

Alternatively, an anti-clockwise turn of $315^\circ$ is equivalent to a clockwise turn of $360^\circ - 315^\circ = 45^\circ$.
Starting from North, a $45^\circ$ clockwise turn leads to Northeast.

The compass will point to Northeast.

The correct option is:
$\text{Northeast}$
