Spheres do not have any perpendicular lines.
Perpendicular: No Parallel: Yes, two pairs.
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.
a regular hexagon
How many pairs of perpendicular sides does this figure have?

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.
10, A decagon has a maximum of five pairs of perpendicular lines, and a maximum of 5 parallel lines. however, this isn't in black and white it can have no pairs of line either perpendicular or parallel. know write the answer clearly
A pentagon can have 0, 1 or 2 pairs of parallel lines. It can have 0 to 4 lines perpendicular to an adjacent line. A rhombus must have two pairs of parallel lines and none of them may be perpendicular to any other.
