Ah, what a happy little question! The shape you're thinking of is a scalene triangle. It doesn't have any lines of symmetry, but it does have rotational symmetry of order 4, which means it looks the same after being rotated 90 degrees four times. Isn't that just lovely?
No
Rotational symmetry is based on points of rotation not lines
The definition of the word "scalene" is a triangle having three sides of different lengths.The mathematical definition of "symmetry" is an exact reflection of form on opposite sides of a dividing line/plane.Therefore, by definition, no lines of symmetry exist in a scalene triangle.
how many lines of symmetry has an equilateral triangle
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.
a scalene triangle has no lines of symmetry
A scalene triangle has no lines of symmetry.

A scalene triangle
Scalene.
An isosceles triangle has 1 line of symmetry, an equilateral triangle has 3 and a scalene triangle has 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.
0 lines of symmetry
No
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.
