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.

Trapezoid, heart, etc.
Yes, they do exist. In fact, there are infinitely many of them.
Shapes that can be divided into two equal parts are called "symmetrical" or "mirror image" shapes. When a shape can be divided into two equal halves that perfectly match each other, it is said to have reflectional symmetry. Examples of such shapes include squares, rectangles, circles, and triangles, as they can be divided into two equal parts along a line of symmetry.
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.
A square has 4 lines of symmetry
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.
There are infinitely many such shapes. To start with, any regular will do.
Triangle, square, circle.
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.
None. A line of symmetry, if it exists, is infinitely long and so a third of the line cannot exist as a separate entity.
