Direction Tests

Concept:Direction changes can be tracked as angular movements from the starting facing direction.Explanation:Start facing South.First turn: $135^\circ$ anticlockwise (to the left).From South, $90^\circ$ anticlockwise leads to East.Another $45^\circ$ anticlockwise from East gives North‑east.After the first turn, he faces North‑east.Second turn: $180^\circ$ clockwise (to the right).From North‑east, a $180^\circ$ clockwise turn points exactly opposite, i.e. South‑west.Alternate net rotation: $180^\circ$ (clockwise) − $135^\circ$ (anticlockwise) = $45^\circ$ clockwise from South, which is also South‑west.Answer:South‑west
