A triangle, in general has none. An isosceles triangle has 1 axis of symmetry while an equilateral triangle has 3 axes.

This could be either an isosceles triangle or a right angled triangle.
An equilateral triangle has 3 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.
It depends. If it is a right isosceles triangle, it has one axis of symmetry (the line which would bisect the right angle). A right scalene triangle has no axis of symmetry.
