ECZ 2024 · O-Level Paper 1 — Geometrical Transformations
The diagram in the answer space shows triangle ABC with vertices A(2, 3), B(4, 2) and C(4, 4). Triangle ABC is mapped onto triangle A1B1C1 under a reflection in the line x = 6. Draw triangle A1B1C1 on the diagram in the answer space.
- A. A1(10, -3), B1(8, -2), C1(8, -4)
- B. A1(6, 3), B1(8, 2), C1(8, 4)
- C. A1(4, 3), B1(2, 2), C1(2, 4)
- D. A1(10, 3), B1(8, 2), C1(8, 4)
Verified working — step 1
Reflection in the line x = 6 maps each point so that x = 6 is the midpoint of the original and image x-coordinates.The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
