It depends you want. For instance, if you were to draw the plus sign then all angles are 90 degrees. There are 2 lines of symmetry. Furthermore, there are 2 straight angles. To conclude there are many characteristics.
Two.
The order of rotational symmetry for a circle is infinite. This is because it can be rotated any amount from the middle and it will still look the same. You can use a special sign to show this: ∞

Let's identify first what a Yield sign is. The Yield sign is the only sign on the road (US) that is in the shape of a upside-down triangle with rounded corners, similarly to the stop sign, the stop sign is the only sign on the road that's in the shape of a octagon (has 8 sides). You'll usually see a Yield sign at an intersection, for instance traffic circles. You're not required to stop at the yield sign but you can if you have too to give way to traffic that doesn't have to stop period. Yield signs are not a sign that you blow through. The yield sign means that "You're not required to stop, but you don't have the right-of-way at this intersection." The yield sign is also less restrictive than the stop sign, you still have to give the right-of-way to other traffic, but you're not required to stop at a yield sign.
A stop sign has 5 more corners than a yield sign. stop sign-8 corners yield sign-3 corners 8-3=5
*traffic signs, (stop sign=octogon, yield=equilateral triangle, do-not-enter=circle, street sign&speed limit=rectangles, etc.) *street lines=rectangle/ parallel lines don't know if this is what you're looking for...?
Two.
you only have to stop at a yield sign if there is cross traffic - if it would not be safe for you to continue through the intersection. Typically only one road at the intersection will have a yield sign - the other one will either have no sign or a stop sign/light.
