What this topic covers

Transformations 1: Translations: Translations described by a column vector.
Transformations 2: Reflections: Reflections in horizontal / vertical / diagonal lines.
Transformations 3: Rotations (incl. combinations involving a rotation): Rotating shapes about a centre and describing rotations fully, including combinations.
Transformations 4: Enlargements (positive scale factor, finding the centre): Enlargement with a positive scale factor and finding the centre of enlargement.
Transformations 5: Harder Enlargements: Enlargements with negative and fractional scale factors.
Transformations 6: Mixed Transformations: Two-step compound transformations.

Transformations worked examples

Worked example 1: Translation

Translate $(3, - 2)$ by the vector $(\begin{matrix} - 5 \\ 4 \end{matrix})$ .

Solution

Add the vector: $(3 - 5, - 2 + 4)$ .
$= (- 2, 2)$ .

3 steps

Tip: Top number moves across, bottom number moves up.

Worked example 2: Reflection in y = −x

Reflect $(4, 1)$ in the line $y = - x$ .

Solution

Reflection in $y = - x$ maps $(x, y)$ to $(- y, - x)$ .
$(4, 1) \to (- 1, - 4)$ .

3 steps

Tip: Check the midpoint (1.5, −1.5) lies on y = −x.

Worked example 3: Rotation about a point

Rotate $(2, 3)$ by $90^{\circ}$ anticlockwise about $(1, 1)$ .

Solution

Vector from centre: $(1, 2)$ .
Rotating 90° anticlockwise: $(a, b) \to (- b, a)$ , giving $(- 2, 1)$ .
Add back to the centre: $(- 1, 2)$ .

4 steps

Tip: Tracing paper is a good check.

Worked example 4: Enlargement from a centre

Enlarge $(5, 2)$ by scale factor 3, centre $(2, 1)$ .

Solution

Vector from centre: $(3, 1)$ .
Multiply by 3: $(9, 3)$ .
Image: $(2 + 9, 1 + 3) = (11, 4)$ .

4 steps

Tip: Always measure from the centre of enlargement.

Worked example 5: Negative fractional enlargement

Enlarge $(4, - 6)$ by scale factor $- \frac{1}{2}$ , centre $(0, 0)$ .

Solution

Multiply the coordinates by $- \frac{1}{2}$ .
$(- 2, 3)$ .

3 steps

Tip: A negative scale factor puts the image on the other side of the centre.

Worked example 6: Combining transformations

Reflect $(2, 5)$ in the x-axis, then rotate the image $180^{\circ}$ about the origin. What single transformation has the same effect?

Solution

Reflect: $(2, - 5)$ .
Rotate 180°: $(- 2, 5)$ .
$(2, 5) \to (- 2, 5)$ : reflection in the y-axis.

4 steps

Tip: Test with a general point (x, y) to be sure.

Where students lose marks on transformations

Examiner's noteGraph transformations of f(x)

Where marks are lost: Reported as a weakness in every series: points are moved the wrong way, or coordinates are read by counting squares rather than using the scale.

Examiners flagged this in 4 exam series (November 2023, June 2024, November 2024, June 2025). Summarised in our own words from Pearson Edexcel examiner reports. Read the full note →

Transformations exam-style questions

Try each question before you open the answer (one has its full worked solution open). The mark schemes use Edexcel-style marks: M for method, A for accuracy (after the method mark), B for an independent result.

Question 1 · easy · 2 marks

Triangle A has vertices (1, 1), (4, 1) and (1, 3). Triangle A is rotated 180° about the origin. Write down the coordinates of the vertices of the image.

Show the answer and mark scheme

B2 (−1, −1), (−4, −1), (−1, −3) (B1 for 2 correct vertices or a correct rotation about a different centre)

Answer: (−1, −1), (−4, −1), (−1, −3)

Question 2 · easy · 1 mark

The point P(3, 5) is rotated 90° clockwise about the origin. Write down the coordinates of the image of P.

Show the answer and mark scheme

Questions students ask

Which Edexcel IGCSE Maths papers test transformations?

Either Higher tier paper, 1H or 2H, can test transformations: both cover the whole Pearson Edexcel International GCSE Mathematics A (4MA1) specification and both allow a calculator. Show your method, because most marks are for working.

Where can I practise more transformations questions?

In the IGCSE student hub: Unit 5 (Geometry) has more exam-style questions on this topic, each with a mark scheme. Practice starts with a 7-day free trial; the worked examples and questions on this page are free.
