angle or inverted bob

I am bobing my hair this week and I want it around chin length on the sides and cut up in the back to the hairline ... is this a angle bob or an inverted bob?  Also I want the back short but is that called stacked or layers.  I don't want the back clipped boy short but want it short.  I did have a plain bob cut and it was like my long hair so I thought if I cut the back short I'll keep it short.  My husband is hoping if I cut the back short I'll give in and get a pixie cut this summer

inverted bob   GO FOR IT!

Rocky posted to insanity's I need advice some pics of the back of what I think is an inverted bob ... the last picture is quite short in back - I printed it off but it's not real clear how do you describe that cut in back =. Thanks and if you go that short in back how long should the sides be.
