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).
The five shapes that have one line of symmetry are equilateral triangle, isosceles triangle, scalene triangle, rectangle, and rhombus. A shape has one line of symmetry if it can be folded along a line so that the two halves match exactly. In the case of these shapes, there is only one line that can divide the shape into two congruent halves.
Yes, they do exist. In fact, there are infinitely many of them.
Well, darling, shapes with only one line of symmetry are like the lone rangers of the symmetry world. We're talking about your squares, rectangles, and isosceles triangles strutting their stuff with just one line to keep them in check. So, if you're looking for a shape that's a bit of a rebel but still plays by the rules, these are the ones for you.
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.
A figure that has rotational symmetry but not line symmetry is a figure that can be rotated by a certain angle and still look the same, but cannot be reflected across a line to create a mirror image of itself. An example of such a figure is a regular pentagon, which has rotational symmetry of 72 degrees but does not have any lines of symmetry. This means that if you rotate a regular pentagon by 72 degrees, it will look the same, but you cannot reflect it across any line to create a mirror image.
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.
square
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.
Such shapes are known as symmetrical.
