No. Objects can have reflective symmetry but no rotational symmetry.
Symmetry was not actually invented. It was just defined after the observation of similarly figured and shaped objects in nature.
Since stars are normally spherical objects, they have rotational symmetry of infinite order.
an animal that has symmetry is a dog or a cat and in nature a four leave clover or a piece of grass.
An equilateral triangle, or curved variations which may be used for paving.
Some objects that have symmetry include butterflies, snowflakes, flowers, and geometric shapes like squares and circles. Symmetry can be seen in both natural and man-made objects.

Symmetry is the line in the middle of any object to split it into two equal parts. some objects or shapes don't always have a 'line' of symmetry.
many objects have no lines of symmetry. for example a wall paper mixed and jumbled with all colours,your heart,a curtain with a number of patterns etc.

None. My picture is not about congruence or symmetry.
