What are the rotational symmetry orders of the following: Parallelogram, Rectangle, Square, Rhombus, Kite and Trapezium? (Note: Trapezium, not Trapezoid)

Answer 1

Parallelogram - 2,
Rectangle - 2,
Square - 4,
Rhombus - 2,
Kite - 1 and
Trapezium - 1

Order of rotational symmetry is the number of times within #360^o# rotation when an object coincides with its original form.

Parallelogram turns into itself after a rotation on #180^o#, Rectangle turns into itself after a rotation on #180^o#, Square turns into itself after a rotation on #90^o#, Rhombus turns into itself after a rotation on #180^o#, Kite turns into itself after a rotation on #360^o#, and Trapezium turns into itself after a rotation on #360^o#.

The rotational symmetry orders for the given shapes are as follows:

Parallelogram: 2 (180 degrees)
Rectangle: 2 (180 degrees)
Square: 4 (90 degrees)
Rhombus: 2 (180 degrees)
Kite: 2 (180 degrees)
Trapezium: 1 (360 degrees)

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
