A regular quadrilateral (which is a square) has both point symmetry and line symmetry.

  • Line symmetry: 4 lines of symmetry (vertical, horizontal, and the two diagonals).
  • Point (rotational) symmetry: rotational symmetry of order 4; it looks the same after rotations of 90°, 180°, 270°, and 360° about its center.

So, if this is a multiple-choice question, the correct option is: “Both point and line symmetry.”
