No, four lines can can have 6 total intersections. They would be Ab, Ac, Ad, Bc, Bd, and Cd

If the lines are straight lines , then there is only one solution, which is the point of intersection of the two lines. It will have ( x,y) coordinates. However, if the lines are curved in any way , there may be more than two or more points of intersection.
The only difference between perpendicular lines and intersecting lines is that perpendicular lines create a right angle at the point of intersection.
Only two - parallel to and halfway between the sides. The diagonals are not lines of symmetry.
In classical or Euclidean plane geometry two points defines exactly one line. On a sphere two points can define infinitely many lines only one of which will represent the shortest distance between the points. On other curved surfaces, or in non-Euclidean geometries, the number of lines determined by two points can vary. Even in the Euclidean plane, two points determine infinitely many lines that are not straight!
