Triangle, square, circle.
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.
A square has 4 lines of symmetry
Shapes that have line symmetry can be divided into two identical halves along a line, known as the line of symmetry. Common examples include squares, rectangles, circles, and equilateral triangles. Irregular shapes can also possess line symmetry if a line can divide them into mirror-image sections. In essence, any shape that can be folded along a line to match both sides exhibits line 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.
Many shapes have more than one line of symmetry. These include a rectangle, equilateral triangle, and a square. While a rectangle has two lines of symmetry, an equilateral triangle has three.

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.
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.
