I'm confused about the vertex of this image.
The question is: What is the vertex of ∠1?

The choices are:
a. Point D
b. Point B
c. Point C
d. Point A

I got A, but when I asked another person to check it, they said that I might be wrong. Any help?
 
I got it.

The vertex is B, I believe. Since the definition was "the point where two rays begin or meet." The picture on the Wiki page helped me a lot as well. I usually have to use outside sources to figure out what the lesson is teaching me, because it's written in a hard-to-learn way. Thank you guys!
