You would call the group of shapes which has at least one line of symmetry symmetrical shapes. Stars, circles, and rectangles are considered symmetrical shapes.
they have what we call "pentaradial" symmetry, but certain species, such as the sand dollar, and the sea cucumber, have a secondary body symmetry, which is a bilateral symmetry
as shape with four sides is generally a squre but a group of shapes with four sides are called quadrelaterals
Two shapes that are the same shape and size are congruent.
Hexagon
You would call them congruent or similar.
When it has no symmetry the object is called asymmetrical.

Well, honey, any shape that looks the same after a 180-degree spin is what we call a shape with 180 degrees rotational symmetry. So, we're talking about shapes like squares, rectangles, and even circles. Basically, if it looks just as good upside down, you've got yourself a shape with 180 degrees rotational symmetry.
Asymmetrical.
