What is unknown?

The quadrilaterals which have both line and rotational symmetry of order more than \(1\).

Reasoning:

To solve this question, you have to use the concept of line symmetry and rotational symmetry. The ‘Line of Symmetry’ is the imaginary line where you could fold the image and have both halves match exactly. Rotational symmetry is when an object is rotated around a centre point (turned) a number of degrees and the object appears the same. The order of symmetry is the number of positions the object looks the same in a  \(360^\circ\) rotation.

Steps:

Square have both line and rotational symmetry of order more than \(1\).
