The question, in short

Find the rotational symmetry order of a six-flag shape, and name a quadrilateral with one line of symmetry and perpendicular diagonals.

Summarised in our own words. Use the official paper for the exact wording and the diagram.

Part (a) · 1 mark

State the order of rotational symmetry of the flag shape shown in the diagram.

  1. 1The pattern of shaded and unshaded flags repeats every 120° (360 ÷ 3)
  2. 2Order of rotational symmetry = 3
