Consider the x and y axes. The intersect in the plane z=0. But if you raise the x axis to y=0, z=1, it will never intersect the y axis defined by x=0, z=0.

do you mean that in the case that x axis is in its original position the x and y axes are perpendicular and intersect, and in the case that the x axis is in y = 0, z = 1 the x and y axes are perpendicular and doesn't intersect ?

Yes. Perpendicular lines only intersect if they lie in the same plane.do you mean that in the case that x axis is in its original position the x and y axes are perpendicular and intersect, and in the case that the x axis is in y = 0, z = 1 the x and y axes are perpendicular and doesn't intersect ?

Yes. That was your question, right? If orthogonal lines must intersect or not.

yes sort of that, if lines with perpendicular directions but the lines themselves are skew, are they considered perpendicular or not, so they are perpendicular, thank youYes. That was your question, right? If orthogonal lines must intersect or not.
