Yes. With one arm pointing straight up, a division down the center will produce two symmetrical halves, each with 2.5 legs.
The letters S and N have point symmetry but not line symmetry.
A parallelogram does not have a line of symmetry.
draw line of symmetry for 20
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.
Because linear symmetry defines a line such that the shape is unchanged when REFLECTED in that line.
do it yourself, think !

Radial symmetry
Well, honey, a starfish is like the Picasso of the ocean - it's all about that funky radial symmetry. They may look like they partied too hard and lost a few limbs, but those five arms are arranged in a symmetrical pattern around a central point. So, yes, a starfish has symmetry, just not the kind you'd find in a boring ol' square.
Most Echinoderms have radial symmetry. Sea Urchins, Starfish, Sand Dollars, etc.
