Stop signs
yes
Octagons can be irregular or regular. It depends on the measure of the angles and the length of a side. An octagon is a shape with 8 sides, not necessarily the regular octagon that stop signs are shaped like.
Octagons have no perpendicular lines.
There are regular octagons, and irregular octagons.
Stop signs
yes
Stop signs are octagons so they will be very easy to recognize, even when partially obscured by vegetation, snow, etc. The stop sigh is the ONLY traffic sign that uses this shape.
Stop signs are one example.
Stop signs are octagons--so 8 sides.
It depends on where you are. For example: Canada has 8 sided stop signs (octagons). If you really want to know go outside and look.

No, not if it is a randomly-drawn 8-vertex shape. Octagons only have all- obtuse angles if it is a regular octagon, like the shape of a stop sign.
Octagons have no perpendicular lines.
There are regular octagons, and irregular octagons.
There are 64 sides in eight octagons.
if we had no stop signs then we would probably have car accidents all the time! stop signs are really important.
