What is it?

Sliding a shape means moving it from one place to another without turning it or flipping it over. Imagine pushing a book across a table – its front stays the front, and its top stays the top. This movement is also called a translation.

Simple Example

Quick Example

Think about a cricket ball sliding across the pitch after being hit. The ball moves from one spot to another, but it doesn't spin or turn upside down during that slide. It just shifts its position.

Worked Example

Step-by-Step

Let's say you have a square drawn on a graph paper, with its corners at (1,1), (3,1), (3,3), and (1,3).
---
Step 1: We want to slide this square 4 units to the right and 2 units up.
---
Step 2: Take the first corner (1,1). To slide it 4 units right, we add 4 to the x-coordinate: 1 + 4 = 5. To slide it 2 units up, we add 2 to the y-coordinate: 1 + 2 = 3. The new point is (5,3).
---
Step 3: Do the same for the second corner (3,1). New x is 3 + 4 = 7. New y is 1 + 2 = 3. The new point is (7,3).
---
Step 4: For the third corner (3,3). New x is 3 + 4 = 7. New y is 3 + 2 = 5. The new point is (7,5).
---
Step 5: For the fourth corner (1,3). New x is 1 + 4 = 5. New y is 3 + 2 = 5. The new point is (5,5).
---
Answer: The new corners of the slid square are at (5,3), (7,3), (7,5), and (5,5).

Why It Matters

Understanding how to slide shapes is fundamental to geometry and understanding how objects move. It's used by animators to move characters on screen, by architects to design buildings, and by engineers to plan how machine parts fit and move together.

Common Mistakes

MISTAKE: Turning or flipping the shape while sliding it. | CORRECTION: Remember, a slide (translation) means the shape keeps the exact same orientation. No turning, no flipping.

MISTAKE: Only sliding one part of the shape, not the whole thing. | CORRECTION: Every point of the shape must move the same distance in the same direction. Imagine the whole shape as one solid piece moving together.

MISTAKE: Confusing sliding with enlarging or shrinking a shape. | CORRECTION: Sliding only changes the position of the shape, not its size or its shape. The new shape is exactly the same as the original.

Practice Questions

Try It Yourself

QUESTION: If a triangle is at position A and slides to position B, does its size change? | ANSWER: No, its size does not change.

QUESTION: A square is drawn with its top-left corner at (2,5). If it slides 3 units to the right and 1 unit down, what are the new coordinates of its top-left corner? | ANSWER: (5,4)

QUESTION: A circle has its center at (4,6). If it slides 2 units left, then 3 units up, and finally 1 unit right, what are the final coordinates of its center? | ANSWER: (3,9)

MCQ

Quick Quiz

Which of the following actions is NOT a slide?

Pushing a dabba (lunchbox) across a table

Moving a mobile phone from one pocket to another

Opening a sliding door

Spinning a top on the floor

The Correct Answer Is:

Options A, B, and C all describe movements where an object changes position without turning or flipping, which is a slide. Spinning a top involves rotation, not just a slide.

Real World Connection

In the Real World

When you use a map app like Google Maps or Ola Cabs, and you drag the map around with your finger to see different areas, you are performing a 'slide' (or translation) of the map. The map itself isn't turning or getting bigger, just moving its visible area.

Key Vocabulary

Key Terms

SLIDE: Moving a shape without turning or flipping it. | TRANSLATION: Another name for sliding a shape. | ORIENTATION: The way a shape is facing. | POSITION: The location of a shape. | COORDINATES: Numbers (like x,y) that tell you the exact location of a point on a graph.
