Rotational symmetry of order 1.
A line has 180 degrees rotational symmetry.
They have not got any rotational symmetry
It depends on which type of cuboid we are talking about. If it is a CUBE (a special type of cuboid), then it has nine planes of symmetry. If it is a cuboid with length, width and height all different, then it has three planes of symmetry. If it is a cuboid with two equal measurements (say width and length), then it has five planes of symmetry.

A cuboid has rotational symmetries of order 2 around each of the three axes going through a pair of opposite faces.
A parallelogram has a rotational symmetry of 2!
triangles have 0 rotational symmetry
it has 5 rotational symmetry

infinite angles of rotational symmetry... (: ~kitty <3 = =
If it's a regular 8 sided octagon then it rotational symmetry to the order of 8
