could this girl like me?

ok in geometry theres this girl who looks at me and when i look at her she quickly looks away i like her but idk if she likes me looks can mean anything but today i noticed when i walked past her twice from the corner of my eye she was looking at me as i walked towards the teacher. i want to ask her could i walk her to her next class and just talk to her on the way BUT the confusing part is everyday she walks out at the end of the class with this same guy everyday. like she shows signs of her liking me im GUESSING but walks with another guy after class. PS eventually im gonna go talk to her
