Common Transformations Mistakes GCSE Maths
Transformations are visual, but they still require careful mathematical detail. Many marks are lost through incomplete descriptions.
Mistakes to Avoid
- Reflecting in the wrong mirror line
- Forgetting the centre of rotation
- Mixing up translation vector directions
- Using the wrong centre of enlargement
Exam tip: After drawing the image, compare distances and orientation with the original shape.
Common mistake: Students sometimes describe a transformation with too little detail to earn full marks.
