A regular pentagon.
a regular hexagon
no shape does! * * * * * Not true. A parallelogram has rotational symmetry of order 2, but no lines of symmetry.
An arrowhead shape has one line of rotational symmetry. This line runs vertically down the center, allowing the shape to be rotated 180 degrees to look the same. It does not have any other lines of symmetry.
A circle has an infinite number of lines of symmetry, corresponding to any of its diameter lines, to any arbitrary level of division (degrees, minutes, seconds).
a pentagon has 5 lines of symmetry
A 2d shape with uncountable lines of symmetry is a circle.
It is called its order of rotational symmetry depending on its shape as for example a square has rotational symmetry to the order of 4 because it returns to its same shape every time of a turn of 90 degrees and so 360/90 = 4
35 lines of symmetry
An equilateral triangle has 3 lines of symmetry
A parallelogram.
There are 3 lines of symmetry ina 6-sided shape.
A square has exactly four lines of symmetry.
