Common Mistakes

X Just saying "rotation" without details Always state centre, angle, and direction Incomplete description loses marks
X Confusing CW and ACW CW = clockwise (like clock hands) ACW = anticlockwise (opposite direction)

Practice Questions for Transformations

A translation is described by the vector (3, −2). What does this mean?

  • A. Move 3 units down and 2 units right
  • B. Move 3 units right and 2 units down
  • C. Move 3 units up and 2 units left
  • D. Move 3 units left and 2 units up

Quick Recall Flashcards

Rotation
State CENTRE, ANGLE, and DIRECTION (CW/ACW). Shape turns around fixed point. 180° is same CW or ACW.
Reflection
State the MIRROR LINE (equation). Shape flips over. Points and images are equidistant from mirror line.
