only one.
None. A isosceles triangle has one line of symmetry and a equilateral triangle has three.
That depends 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 and any other triangles have no lines of symmetry.
Any isosceles triangle that is not also equilateral has exactly one line of symmetry.
