No, it does not.
No.
It has rotational symmetry of order 2.
The triskelion (the three legs) on the Isle of Man flag.
Yes, for example the triskelion (the three legs) on the Isle of Man flag.
The flag of Nepal is unique in that it features a symmetry line down the middle, with two distinct shapes: a crimson red background and blue borders, each containing a white emblem. The two shapes, a moon and a sun, exhibit rotational symmetry. The flag's design is non-rectangular, making it the only national flag that is not quadrilateral. Overall, Nepal's flag stands out for its combination of symmetry and symbolic shapes.
No.
It has rotational symmetry of order 2.
Triangle * * * * * The only triangle with rotational symmetry of order 3 is an equilateral triangle and that has 3 lines of symmetry, not 0. The triskelion (the three legs) on the Isle of Man flag has rotational symmetry of order 3 but no lines of symmetry.

The triskelion (the three legs) on the Isle of Man flag.
For example the triskelion (the three legs) on the Isle of Man flag.
Scalene triangle * * * * * A scalene triangle does not have rotational symmetry of order 3. The triskelion (the three legs) on the Isle of Man flag, or a simplified version of that shape will meet the requirements.

It has 8lines of rotational symmetry
A trapezoid has no rotational symmetry.
Equilateral triangles have rotational symmetry.
