I thought about drawing a line but that wouldn't make angle. An angle needs two rays right?

I checked my notes and according to them 180 is not the right answer. It would be a straight angle not zero. I'm so going to fail my geometry test on Wednesday.

About that infinitive line....
That wouldn't be an angle then if there's no vertex

Those people know nothing about math. Aline would be 180 degrees. A ray is actually 0 degrees if you draw accurately. How? Like this: •——————►
A 0 degree angle would be two rays closing on each other so you should be able to only see one ray. If you don't put your vertex at the end of either end, it would be a straight angle (180 degrees). Hope this helps.

If you draw a ray and superimpose another ray exactly on top of it then you have drawn two lines with an included angle of zero.
If you draw two rays that are parallel then you have an included angle of zero degrees as well.
If you draw two rays that are co-linear but, running in the opposite direction then you have drawn an angle of 180 degree.

drawing a line is fine. it just as if they were two lines, but you cannot distinct one to each other, because they are the same.
but be aware that your picture would potentially represent an angle of pi, i.e. 180 degrees to (and all multiples of pi)
I suggest you label the points at the extremity, so that in the case of pi there are three points and you say this is the angle between BC and BA for example. But there is still an indetermination with respect to the sign of the angle. In your case there is not, because there is only two points, one with the label B, and one with the labels A and C. Am I clear ?

Well, look at a cartesian axis (coordinate grid with x and y axis). 0 Degrees is defined to be the positive x axis. 90 to the left, and you get the positive y axis. Another 90 left, the negative x axis and so on. Technically speaking, a 0 degree angle is a straight line, but do not confuse it with 180 degree angle.

0 degrees would be represented as two coincident rays pointing the same direction.
On paper it would look like a single ray:

The attached link also shows a zero degree angle.

a line would equal 180 degrees I do know that. I don't think you can have a zero degrees angle.

Sounds like a trick question. I suppose you'd draw a finite line(ray). The two rays you need are just on top of each other so it looks like one ray.

Simply drawing a straight line, while it sounds too easy, would be correct.

The only way to truly represent a zero degree angle is two rays that share an endpoint and totally overlap...

where o represents the endpoint.

You just draw a straight line. That is how you do a 0 degree line
