In general, none.
There is no such word as a dectagon. And since it could refer to an octagon or a decagon (or possibly something else), it is not possible to give a sensible answer. Please correct your spelling and resubmit the question. If either octagon or decagon, they need not have any parallel lines.
A decagon need not have any lines of symmetry. It can also have 1 or 10 lines of symmetry.
A decagon need not have any lines of symmetry. It can have 10.
An irregular decagon has no lines of symmetry. Unlike a regular decagon, which has 10 lines of symmetry due to its equal sides and angles, an irregular decagon lacks uniformity in its shape, meaning that it cannot be divided into identical halves by any line. Therefore, it generally has zero lines of symmetry.
Ten.
A regular decagon would have five sets or parallel lines.
A regular decagon will have 5 pairs of parallel sides, however, irregular decagons can have no parallel sides.
A decagon has 10 sides. Any regular polygon with four or more sides will have pairs of sides that are parallel. A decagon will have 5 pairs of parallel sides.

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

Here are three shapes that have two pairs of parallel lines: square parallelogram rectangle There are many polygons with at least two pairs of parallel lines. hexagon (has 3 pairs of parallel lines) octagon (has 4 pairs) decagon (has 5 pairs)
A decagon need not have any lines of symmetry. It can also have 1 or 10 lines of symmetry.
There are 10 parallel lateral edges. And ten parallel edges between the two bases. There could be more - within each decagon, but that depends on the decagons, and details of these are not given.
