An octagon has 8 sides

An octagon has the same number of corners as sides. So, an octagon which has 8 sides has 8 corners.
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.

8 sides. octagon is referring to the number eight.
An octagon has the same number of corners as sides. So, an octagon which has 8 sides has 8 corners.
An octagon has the same number of corners as sides. So, an octagon which has 8 sides has 8 corners.
There are no perpendicular lines in a regular octagon. Perpendicular lines are found in squares and rectangles, where the angles are 90 degree angles. Regular octagons, unlike squares, have so many sides that the angles joining the sides cannot be as sharp as 90 degrees. Instead, the angles are much larger and the sides are much too wide apart to be anywhere near perpendicular. It is possible, however, to construct an irregular octagon having perpendicular lines.
A concave hexagon can have 6 perpendicular sides if you count the external angle of one. The angles would be 90, 90, 90, 90, 90, 270
