It need not have any.
A dodecahedron has 0 parallel faces
A right angle has no parallel lines, but it does have perpendicular lines that meet at right angles.
A trapezoid has one pair of parallel sides, which are its bases. The other two sides, called the legs, are not parallel and can be either perpendicular or slanted, depending on the specific type of trapezoid. In summary, a trapezoid has one pair of parallel lines and zero perpendicular lines by definition.

It need not have any.
A trapezoid has 2 parallel lines. It may or may not have perpendicular lines.
None but it does have perpendicular lines
A dodecahedron has 0 parallel faces
A parallelogram has 2 pairs of parallel lines and in the form of a rectangle it has 2 pairs of parallel lines and 4 perpendicular lines that meet at each of its corners at right angles.
A right angle has no parallel lines, but it does have perpendicular lines that meet at right angles.
none
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
There are no parallel lines in any triangle but a right angle triangle has perpendicular line that meet each other at 90 degrees.
Perpendicular lines = lines which are at right angles (90 degrees) to each otherDiamond = 2 pairs of parallel lines
