They are simply four pairs of perpendicular lines. There is nothing in the question to suggest there is anything more than that to them.
Perpendicular to what? Four pairs cannot be mutually perpendicular unless you go into hyperspace.

The rectangle has four corners.Every corner is a right angle.Every right angle is a place where two perpendicular lines meet.Looks like the rectangle has four pairs of perpendicular sides.

Spheres do not have any perpendicular lines.
Perpendicular: No Parallel: Yes, two pairs.

Can have no pairs or one pair...
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.

Perpendicular lines intercept each other at right angles which is 90 degrees
