Introduction
Direction-based puzzles are a key part of logical reasoning for Standard 4. These questions test spatial orientation and the ability to visualize movements in different directions.
Explanation Step by Step
To solve these puzzles, visualize the standard compass rose:
- North: Upward
- South: Downward
- East: Right
- West: Left
Sub-topics
Direction Sense
This includes movements relative to the sun (sunrise/sunset) and understanding how positions change during physical activities like Yoga (Shirshasana).
Examples
Example 1
Tricks and Shortcuts
During an inverted position (Shirshasana), if your face is toward a direction, your left and right hands swap their relative directions compared to a standing position.
Common Mistakes
Students often confuse clockwise and anti-clockwise turns. Always draw a small compass on your rough sheet to avoid errors.
Practice Questions
Easy Questions
- If you are facing the rising sun, which direction is behind you?
- Which direction lies exactly opposite to the North-West direction?
- A person is facing South. If they turn to their left, which direction will they face?
Medium Questions
- While performing Sun Salutation (Surya Namaskar), if you turn to your right twice at right angles, which direction is behind you?
- A boy is performing a headstand (Shirshasana) facing West. In which direction will his left hand point?
- Starting from the North, if you turn 90 degrees clockwise three times, which direction are you facing?
Hard Questions
- Santosh is in an inverted position with his face towards North-West. If he extends his left hand, which direction will it show?
- A person walks North, turns 90 degrees right, walks, and again turns 90 degrees right. What is the direction of their back now?
- If South-East becomes North and North-East becomes West, what will West become?
Revision Summary
Mastering direction puzzles requires knowing the 8 directions and understanding how turns and inversions affect left-right orientation.
