- A4 lines of symmetry and rotational symmetry of order 4
- B2 lines of symmetry and rotational symmetry of order 4
- C2 lines of symmetry and rotational symmetry of order 2
- D1 line of symmetry and rotational symmetry of order 2
Step-by-Step Solution
Only the two diagonals are lines of symmetry for a rhombus; the lines through the midpoints of opposite sides are axes of symmetry only when the rhombus is a square. Turning it through 180° about the centre maps it onto itself, and a quarter turn does not, so the rotational symmetry has order 2.
Answer: C) 2 lines of symmetry and rotational symmetry of order 2
