Paper 22 Q10(a)IGCSE 0580 May/June 2023

Question

Describe fully the single transformation that maps shape A onto shape B.

This question tests your ability to identify and describe transformations by comparing two shapes on a coordinate grid. Recognising the type of transformation and finding its exact details is essential for geometry problems.

Step-by-Step Solution

Key Takeaway

For reflections, you must identify both the transformation type and the exact equation of the mirror line to earn full marks.

Common Mistakes

Writing just 'reflection' without specifying the mirror line - this only earns 1 mark out of 2
Confusing the mirror line with y = -2 or x = 2 by misreading the coordinate grid or not checking carefully enough

Exam Tip

Always check your mirror line by picking a point on shape A and verifying that its reflection across your proposed line gives the corresponding point on shape B.
