A four-pointed star with rotational symmetry of 90° and all 8 sides congruent exhibits both line symmetry and point symmetry.
-
Line Symmetry: The star can be divided into identical halves along certain axes. It typically has four axes of symmetry that go through the points of the star and the midpoint of the opposite side.
-
Point Symmetry: The star has a center point about which the star can be rotated (180°) and still look the same.
Therefore, the correct response is both.
