What does "Sun trine Lilith" mean in a birth chart?

What does "Sun trine Lilith" mean in a birth chart? Is it good or bad? Also, I have Lilith in Cancer based in my birth chart, and I don't know what does this mean because I don't act/feel like a Cancer at all. I act/feel like a complete Aquarius to be honest. I don't see myself as a Cancer at all. So I was wondering and curious about this astrological placement. Can anyone please explain to me?
