Equilateral.
Rotational symmetry 2 1 as it is then the second when it is turned half way of a full turn.
bilateral and rotational symetry
It has rotational symmetry of infinite order as well as an infinite number of axes of symmetry.
a starfish has a rotational symmetry because it rotates back to itself 90 degrees which is 1/4 of a turn.
An equilateral triangle has both line symmetry and rotational symmetry. A non-equilateral isosceles triangle has line symmetry but not rotational symmetry. A scalene triangle has neither kind of symmetry.
Irregular shapes don't ever have rotational symmetry.

It only has rotional symmetry if it can be rotated around a point less than 360 degrees and staying the same shape like if you rotate a square 90 degrees it will be the same shape as in the beginning.. Kind of confusing

Yes, a smiley face does have rotational symmetry. Rotational symmetry means that an object looks the same after a certain degree of rotation. In the case of a smiley face, if you rotate it 180 degrees, it will still look the same. This is because the eyes, nose, and mouth are symmetrically arranged around the center of the face.
Shapes with rotational symmetry can be rotated around a central point and still appear the same at certain angles. Common examples include circles, squares, equilateral triangles, and regular polygons, which maintain their appearance when rotated by specific degrees (e.g., 90 degrees for a square or 120 degrees for an equilateral triangle). The order of rotational symmetry refers to how many times the shape matches its original position in one full rotation (360 degrees).
Their early larvae have bilateral symmetry, but as they get bigger they develop fivefold symmetry. This is apparent in the regular sea urchins, that have roughly spherical bodies, with five equally sized parts radiating out from their central axes.
