No.
Not necessarily, except rotational symmetry of order 1.

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.
Rotational symmetry refers to symmetry of the figure when it is rotated about a single point in the same plane. Lines of symmetry apply to reflections. You do not have lines of rotational symmetry.
Yes, the capital letter N has rotational symmetry but no lines of symmetry:
First of all, your grammar is terrible. The question should be "Does a triangle have 2 lines of symmetry and 2 lines of rotational symmetry? and the answer is no. A triangle can not have 2 lines of rotational symmetry, because you only rotate the image, you do not use any lines.
Rotational symmetry is based on points of rotation not lines
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.
Not necessarily, except rotational symmetry of order 1.
how many lines of symmetry has an equilateral triangle
None.
