Circle
a pentagon has 5 lines of symmetry
An equilateral triangle has 3 lines of symmetry
A parallelogram.
It depends on the exact shape. Not 8, but there can certainly be 1.
Circle
They may have no lines of symmetry or they may have some - it all depends upon the shape of the irregular octagon. Only regular octagons have 8 lines of symmetry.
no shape does! * * * * * Not true. A parallelogram has rotational symmetry of order 2, but no lines of symmetry.
a pentagon has 5 lines of symmetry
A 2d shape with uncountable lines of symmetry is a circle.
35 lines of symmetry
An equilateral triangle has 3 lines of symmetry
A parallelogram.
There are 3 lines of symmetry ina 6-sided shape.
It depends on the exact shape. Not 8, but there can certainly be 1.
The number 8 has an infinite number of lines of symmetry. It is symmetrical both vertically and horizontally, as well as along diagonal lines that pass through its center. This symmetry occurs because the shape can be reflected or rotated in multiple ways while maintaining its appearance.
A square has exactly four lines of symmetry.
