An isosceles triangle and an isosceles trapezoid are two of them.
they can but not all shirts have a line of symmetry for example an assymetrical shirt doesnt have a line of symmetry
Symmetry
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.
The only known shapes with two lines of symmetry are rhombus and rectangles. These shapes are found by the test of line of symmetry of certain shapes.Sketch a rectangle, which has two pair of congruent and parallel lines and all right angles. Indicate the lines of symmetry. They should pass through each opposite midpoint of the segments of the rectangles.Sketch a rhombus, the shape that has all congruent sides, but have two pairs of congruent angles, which are different from another. Indicate the lines of symmetry. They should pass through both opposite vertices of the rhombus.
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.
It all depends what types of shapes, but take for example a circle, it can have multiple lines 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.
not all shapes have lines of symmetry. one example is a triangle.
isoceles triangle
square
A square dies because you can fold it across 😜.
There would be too many to name. All regular polygons have a line of symmetry, but there are still polygons that don't.
There are infinitely many such shapes. To start with, any regular will do.
Triangle, square, circle.
