Definition
What is it?
The 'left side' refers to the part of an object, person, or equation that is to the left when you are facing it or looking at it from a specific viewpoint. It's one of two main directions, opposite to the right side.
Simple Example
Quick Example
Imagine you are standing in front of your school gate. The side of the gate where the watchman usually sits, if it's towards your left hand, is the left side of the gate. If you point with your left hand, that's the direction of the left side.
Worked Example
Step-by-Step
Let's find the left side of a cricket bat.
1. Hold a cricket bat in front of you with both hands, as if you are about to play a shot.
2. Extend your left hand straight out from your body.
3. The part of the bat that is directly in line with your extended left hand is the left side of the bat.
4. If you were looking at the bat from the umpire's perspective, the side facing your left hand would be its left side.
Answer: The side of the cricket bat aligned with your left hand is its left side.
Why It Matters
Understanding 'left side' is fundamental for giving and following directions, reading maps, and even understanding how machines work. It's crucial in fields like medicine (identifying body parts), engineering (designing structures), and even in sports for positioning players.
Common Mistakes
MISTAKE: Confusing left and right, especially when someone else is giving directions. | CORRECTION: Always use your own left hand as a reference point. If someone says 'your left', think 'my left hand side'.
MISTAKE: Assuming the 'left side' of an object is always the same, regardless of your viewing angle. | CORRECTION: The 'left side' can change based on your perspective. What's left for you might be right for someone facing you.
MISTAKE: Not understanding 'left side' in mathematical equations. | CORRECTION: In maths, the 'left side' (LHS) is everything written to the left of the '=' sign. It's the expression whose value you often need to find or compare.
Practice Questions
Try It Yourself
QUESTION: If you are sitting on a bus and the window is on your left, which side of the bus is the window on? | ANSWER: The left side.
QUESTION: Your friend is sitting opposite you at a table. If you point to your left, which direction is your friend pointing if they also point to their left? | ANSWER: Your friend would be pointing to your right.
QUESTION: In the equation 5 + x = 12, what is on the left side of the equals sign? | ANSWER: 5 + x
MCQ
Quick Quiz
When you are facing a blackboard in your classroom, which part of the blackboard is on your left?
The part closest to the door if the door is on your right
The part closest to your left hand
The part closest to the teacher's desk
The part closest to the window, regardless of its position
The Correct Answer Is:
B
The 'left side' is always relative to your own body. So, the part closest to your left hand is the correct answer. The other options depend on external factors.
Real World Connection
In the Real World
When you use a navigation app like Google Maps or Ola/Uber, the directions 'turn left' are crucial for reaching your destination. Traffic police also use 'keep left' signs to guide drivers, especially in India where we drive on the left side of the road.

What to Learn Next
Now that you understand 'left side', you should learn about the 'Right Side'. These two concepts are often used together and are essential for understanding spatial relationships and directions in more complex problems.
