A man walks down the backside of his house straight 25 metres, then turns to the right and walks 50 metres again; then he turns towards left and again walks 25 metres. If his house faces to the East, what is his direction from the starting point?

1. **Establish Start Direction**: The house faces East. Therefore, the backside faces **West**. The man starts walking towards the West. (Concept: Orientation Logic [60])\n\n2. **Analyze Components of Motion** (Using Net Displacement Logic [55]):\n - **Move 1**: 25m **West**.\n - **Turn 1**: He turns Right. From West, a right turn points **North** (Concept: Relative Turns [28]). He walks 50m **North**.\n - **Turn 2**: He turns Left. From North, a left turn points back to **West**. He walks 25m **West**.\n\n3. **Summation**:\n - Total East-West Movement: 25m West + 25m West = **50m West**.\n - Total North-South Movement: **50m North**.\n\n4. **Final Direction**: The person is located at a point that is both West and North of the starting point. Therefore, the direction is **North-West**.
