Translation in Four Moves
1
Read the Vector
Identify the horizontal and vertical movement shown by the translation vector.
2
Move Horizontally
Use the first vector value: positive moves right and negative moves left.
3
Move Vertically
Use the second vector value: positive moves up and negative moves down.
4
Plot and Check
Plot every translated point and check that size, shape and orientation are unchanged.
What You’ll Learn
Understand what a translation is.
Recognise the key features of translations.
Read and interpret translation vectors.
Use positive and negative vector values.
Translate points and complete shapes.
Describe a translation using a vector.
Distinguish translations from other transformations.
Key Rules
Translation vector
A translation is described using a vector showing horizontal and vertical movement.
First number
The first number shows horizontal movement: positive = right, negative = left.
First number
The first number shows horizontal movement: positive = right, negative = left.
Using the radius
Arc Length = (Angle ÷ 360) × 2πr
Shape stays unchanged
A translation keeps the same size, shape and orientation. Every point moves the same distance in the same direction.
Worked Proof: Translation
Key Features of Translations
- The shape keeps the same size.
- The shape keeps the same shape.
- The shape does not rotate.
- The shape does not flip.
- Every point moves the same distance in the same direction.
More Worked Examples
1
Translate the point (5, 7) by the vector (-2, 3).
Move 2 units left and 3 units up.
= (3, 10)
- Common GCSE Mistakes
- Confusing left and right movement.
- Moving the shape the wrong distance.
- Confusing positive and negative values.
- Rotating the shape accidentally.
- Writing vectors incorrectly.
- Exam Tips
- Read the horizontal vector value first.
- Positive horizontal values move right; negative values move left.
- Positive vertical values move up; negative values move down.
- Keep the shape’s size and orientation unchanged.
- When describing a translation, state the vector clearly.
