I don't think a human foot has any lines of symmetry. I don't know about other species.
symmetry is appealing to the human eye. Even humans choose their mates according to symmetry. That's bcoz for example- males with broad shoulders etc are more symmetrical than those without See link below "Symmetry" for better info
Line symmetry = Reflection symmetry. Point symmetry = Rotational symmetry.
It depends on what kind of shape you are asking about. A circle has an infinite number of lines of symmetry, all passing through the center. Regular shapes (triangle, square, rectangle, pentagon, etc.) have at least one. Irregular shapes tend to have no line of symmetry.
Symmetry is often seen everyday by people of all ages in nature. Symmetry that we see everyday in nature is most often Bilateral Symmetry. This means that the two halves of an object are exactly mirror images of each other. Symmetry in humans the human face has a line of symmetry in some places, but some faces are more symmetrical than others. The more symmetrical your face the prettier your face will appear. A perfect example of this is supermodels and actresses. Another example of human symmetry is the kidneys, lungs, and the brain. If you draw a line or slice these organs in half, you will have a mirror image of the other. In flowers there are roughly identical petals, sepals, stamens, and leaves. While at the beach there are a wide variety of shells and underwater life with a line of symmetry, an example of this is a crab, a lobster, octopus, and starfish. Crystal G.
Radial symmetry is a particular kind of symmetry in which an object takes on a similar form in any direction outward from the center (like a circle, which is the most perfect radially symmetrical form). Another form of symmetry is bilateral symmetry, meaning that is a two sided symmetry, in which a left side resembles a right side; this is the kind that human bodies have. In comparison, starfish have radial symmetry.
