infinite angles of rotational symmetry... (: ~kitty <3 = =
A general parallelogram has rotational symmetry of order two.
A scalene triangle has one order of rotational symmetry.
It has rotational symmetry order 2. Its is also known as a diamond and is a special type of rectangle
It depends on the type of triangle. A scalene triangle (no equal sides) has no rotational symmetry. An isosceles triangle (2 equal sides) has rotational symmetry order 2. An equilateral triangle (3 equal sides) has rotational symmetry order 3. The order of rotational symmetry is how many time a shape will fit over itself during one complete rotation.
