Direction Sense – Reasoning Ability
Puducherry TET (Teacher Eligibility Test)
1. Simple Explanation
Direction sense tests a candidate’s ability to understand and work with spatial relationships.
- Cardinal directions – North (N), East (E), South (S), West (W)
- Relative directions – front, back, left, right, and intermediate points such as NE, SE, SW, NW
- Turning & rotation – 90°, 180°, 270° turns, clockwise (CW) or anticlockwise (ACW)
- Positioning – Understanding where one object is in relation to another (e.g., “X is to the right of Y” or “Z is behind X”).
Typical TET questions give a diagram or a set of statements and ask you to deduce the position of a particular point or the direction in which a person is facing.
2. Key Points to Remember
| Concept | What it Means | How to Apply |
|---|---|---|
| Cardinal Directions | N, E, S, W – the four main axes on a map | Use a mental compass; N is up, E is right, S is down, W is left |
| Intermediate Directions | NE, SE, SW, NW – halfway between two cardinal points | Think of them as “upper‑right”, “lower‑right”, etc. |
| Relative Positioning | “X is to the right of Y” → X lies east of Y | Always keep the “reference point” fixed while moving to the stated direction |
| Turning | 90° turn = one cardinal direction shift; 180° = opposite direction | When a person turns, update their facing direction accordingly |
| Clockwise vs Anticlockwise | CW = N → E → S → W → N | Useful when multiple turns are involved |
| Behind/Front | “Behind” means opposite to the facing direction | If a person is facing North, “behind” is South |
| Diagonal Relationships | “Upper‑right” = NE | Combine two cardinal moves (N + E) |
| Symmetry & Reflection | When two objects mirror each other, directions reverse | Helpful for “opposite” questions |
3. Worked Example
Problem (Typical TET style)
In a diagram, points A, B, C, D, E, and F are placed as follows:
- B is directly north of A.
- C is to the right of B.
- D is to the left of C.
- E is directly south of D.
- F is at the same position as A.
Question: If a person is standing at point C and looking towards D, in which direction is the person facing?
Step‑by‑Step Solution
| Step | Reasoning | Diagram (ASCII) |
|---|---|---|
| 1. Place A | Let A be at the origin (0,0). | A (0,0) |
| 2. B north of A | Move up 1 unit. | B (0,1) |
| 3. C right of B | Move right 1 unit. | C (1,1) |
| 4. D left of C | Move left 1 unit → back to B’s position. | D (0,1) |
| 5. E south of D | Move down 1 unit. | E (0,0) |
| 6. F same as A | F (0,0) (not needed for the question) |
|
| 7. Direction from C to D | C (1,1) → D (0,1) → move west. | Person at C facing West |
Answer: The person at C, looking toward D, is facing West.
4. Quick Revision Summary
| Topic | Quick Tips |
|---|---|
| Cardinal & intermediate directions | Remember a mental compass: N (up), E (right), S (down), W (left). NE = up‑right, etc. |
| Relative positioning | Keep the reference point fixed; move to the stated direction. |
| Turning | 90° = shift one step on the compass; 180° = opposite. |
| Behind/Front | Behind is opposite to the facing direction. |
| Common patterns | 1) “X is to the right of Y” → X east of Y. 2) “X is behind Y” → X south if Y faces North. |
| Diagram reading | Start from a known point, place others step‑by‑step, then answer. |
| Practice | Draw 2‑3‑point diagrams for each statement; always check the final orientation. |
Final Quick Checklist
- Identify all given relationships.
- Choose a fixed origin (usually the first point).
- Translate each statement into a coordinate move.
- Keep track of directions after each move.
- Answer the question using the final coordinates or orientation.
