Mini square loop from A: 1–1–1 km legs: Mohan: South 1 km → left 1 km → left 1 km. Which direction is he facing now?

Introduction / Context:
Three one-kilometre legs forming three sides of a unit square; determine the final heading.

Given Data / Assumptions:

• Start South 1.
• Left from South ⇒ East 1.
• Left from East ⇒ North 1.

Concept / Approach:
Two left turns from South progress heading to North.

Step-by-Step Solution:

Verification / Alternative check:
Visualising the square confirms the final leg heads up (north).

Why Other Options Are Wrong:
East/West/South-West do not match the final left from East.

Common Pitfalls:
Confusing “where he is” with “what he is facing.” Here we need the heading.

Final Answer:
North
