if you are talking about a geometric figure its the octagon
Two.
A cube is one of them.
An octagon need not have any sides that are vertical.
where the sides are vertical.
what is a shape that have 8 sides
A regular octagon has 8 sides and 8 vertices. To determine the number of vertical lines that can be drawn through its vertices, we consider the symmetry of the shape. In a regular octagon, there are 2 vertical lines of symmetry that can be drawn through pairs of opposite vertices. Therefore, there are 2 vertical lines in a regular octagon.
measure one side and BOOM there you have it length is probably the vertical sides
Do you mean vertical parallel sides? I think there is 4.
