ECZ 2013 · O-Level Paper 1 — Geometrical Transformations
In the diagram, triangle A is mapped onto triangle B by a single transformation. Describe fully the transformation.
- A. Rotation of 90° clockwise about (2, 2)
- B. Reflection in the line y = -x
- C. Reflection in the line y = x
- D. Rotation of 90° anticlockwise about (2, 2)
Verified working — step 1
Compare coordinates point by point - every (x, y) lands on (y, x), the signature of one particular mirror.The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
