Usually none, but all ten can be perpendicular.
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 Star has 0 perpendicular lines!
9 perpendicular lines
There can be up to 8 perpendicular lines.
0 perpendicular lines. There are no 90 degree angles within a hexagon. Perpendicular lines meet at a right angle and sometimes they intersect.

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.
A regular decagon would have five sets or parallel lines.
A decagon, which is a ten-sided polygon, can have a varying number of perpendicular sides depending on its specific shape. In a regular decagon, no sides are perpendicular to each other, as all angles are equal and measure 144 degrees. However, in irregular decagons, the number of perpendicular sides can vary. Therefore, the answer is that a decagon can have zero or more perpendicular sides, depending on its configuration.
10 lines of symmetry
Octagons have no perpendicular lines.

An octahedron has 7 perpendicular lines.
There are four perpendicular lines in a rectangle
Each of the four lines is perpendicular - to two of the other lines.
