Did she get mad at me.?

There is this girl that i like. I don't know if she likes me or not. We would always smile at each other at school and will have good conversations. I was with my friends and we started to talk about her. I told my friends that she has allot of hot friends. When i said that she has allot of hot friends i didn't realize she was really close by me walking. I asked her how she is doing and she said she is ok but she looked mad and we didn't really talk because she walked away without saying bye. I think she heard me talking about her hot friends with my guy friends. If a girl that you like hears you talking about her friends and gets mad at you because you said she has hot friends can that be a sign she she likes you.
