How to interpret Ancestry.com match?

I recently got a new match on Ancesrty.com indicating a close family relationship that I don't recognize nor have ever heard of (nor has anyone else in my immediate family). I've posted the info from this new match (image #1). I've also posted the info from my Aunt (image #2). Both relations are from the paternal side of my family. I'm not understanding what the values (cM's, segments, segment length, ect.) are representing and how they relate to family relationships. Thanks in advance for the insight that anyone can share on this matter.
