* * * * *
The above answer was written by someone who does not know the difference between a decagon (10 sides) and a dodecagon (12 sides).
A dodecagon need not have any parallel sides. It can have 1, 2, 3, 4, 5 or 6 pairs.
It can have 1, 2, 3 or 4 triplets; 1, 2 or 4 quartets or 2 sextets. It can also have combinations like 2 pairs and 1 triplet.

How many pairs of parallel sides does a decagon have?
It has 3 pairs of parallel sides By the way parallel sides are sides that never intersect (meet or touch together)
How many pairs of parallel sides does a quadrilateral have?
A quadrilateral has 4 sides, 2 in which never intersect. Therefore, the lines that don't intersect are called parallel. There are 4 parallel sides but has 2 pairs of parallel sides.
How many pairs of parallel sides does a circle have?
A circle does not have any pairs of parallel sides. In geometry, parallel sides are defined as sides that are always the same distance apart and will never intersect. Since a circle is a curved shape with no straight sides, it does not have any pairs of parallel sides.
How many pairs of parallel sides are there in square?
