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.
None.
A triangle having each of its three sides of different lengths is a scalene triangle. That would also mean there are no lines of symmetry.
That will depend on what type of triangle it is because an equilateral triangle has 3 lines of symmetry whereas an isosceles triangle has only 1 line of symmetry but a scalene triangle has no lines of symmetry.
