bilateral (left and right sides look alike)
asymmetry (no sides look alike; it's uneven)
radial symmetry (you can divide it in half lots of ways and have the pieces look alike)

fork: Bilateral
(symmetry with respect to the axis along the length of the fork)

Jagged piece of rock: Asymmetry

Rubber ball: Radial
(meaning that it is symmetric with respect to any plane that passes through its center)
