No! An Octagon that is not regular can have 8 lines that meet at any angle provided that they ultimately create an 8 sided enclosed shape.
A regular Octagon, however, will always have pairs of sides that are perpendicular. In a regular Octagon the interior angles must all be equal and must sum to 1080 degrees (6 x 180 degrees). Accordingly the interior angles will all equal 135 degrees. As a consequence the exterior angles equal 45 degrees and since two exterior angles equal 90 degrees every side will be perpendicular to the sides that are adjacent but one in either direction. Likewise opposite sides (4 exterior angles apart) will be parallel.

If it is regular, yes. Each side of a regular octagon has two other sides that are perpendicular to it.
A rhombic octagon. An ordinary regular octagon does have perpendicular sides. They do not meet in the outline of the octagon because they are alternate, but they are still perpendicular. However, in the same way that a rhombus is a distorted square, a rhombic octagon can have 4 pairs of parallel sides but no perpendicular ones.
No . It is not perpendicular
octagon has eight sides
A hexagon has 6 sides. An octagon has 8 sides.
A polygon with 8 sides is an octagon.

A rectangle always has perpendicular sides.
How many pairs of perpendicular sides does this figure have?
Yes, because an octagon always has eight sides and a hexagon always has six.
A regular octagon has eight equal sides, but in general the sides of an octagon don't have to be equal as long as there are eight of them.
a rectange
No . It is not perpendicular
A rhombus has 4 equal sides and the diagonals are always perpendicular
Perpendicular
