Only one line of symmetry, it is the line that contains the median of the isosceles triangle (that passes through the vertex and perpendicular to the base).
usually none
It varies depending on the angles and lines of the triangle.

There can be only one pair of perpendicular lines in an isosceles triangle when it is a right angled isosceles triangle. A non right angled isosceles triangle has no pairs of perpendicular lines.
usually none
1 line of symetry
An isosceles triangle has only 1 line of symmetry.
