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.
It all depends what types of shapes, but take for example a circle, it can have multiple lines of symmetry.
None. A line of symmetry, if it exists, is infinitely long and so a third of the line cannot exist as a separate entity.
A square has 4 lines of symmetry
There could be many answers to this. If were thinking in terms of geometry: a triangle has between 1 and 3 lines of symmetry a square will always have 4 lines of symmetry. Irregular shapes might have a single line of symmetry. For instance, a building may have a single line of symmetry. a line between two points may only have one line of symmetry. because it is only 2 dimensions, it is impossible for it to have more than one line of symmetry.

All regular shapes have a line of symmetry. But you can get rid of its line of symmetry by making it irregular (so the angles aren't the same).

Shapes do not always have lines of symmetry. For example, if you have an irregular shape, it will not have a line of symmetry. I am quite certain though that all geometric shapes have a line of symmetry.
No. Asymmetric shapes do not have any lines (or planes) of symmetry.
None. A line of symmetry, if it exists, is infinitely long and so a third of the line cannot exist as a separate entity.
A square dies because you can fold it across 😜.
An isosceles triangle and an isosceles trapezoid are two of them.
A square has 4 lines of symmetry
Yes, they do exist. In fact, there are infinitely many of them.
A nonrectangular parallelogram has rotational symmetry, but not line symmetry. Additionally, shapes such as the letters S, N, and Z can be rotated to show rotational symmetry, although they do not have line symmetry.
