30 degrees off square?? Help plz

HI,
I am making the doll picnic table with my son, and I have never seen directions that said 30 degrees off square. Does that just mean a 30 degree angle?

Here is a copy of the cut list:
TABLE
5 - 1x2 @ 17 3/4"
3 - 1x2 @ 7 1/2" (Long point to long point, both ends cut at 30 degrees off square, NOT parallel)
2 - 1x2 @ 8 3/4" (Both ends cut at 30 degrees off square, ends are parallel)
2 - 1x2 @ 7 7/8" (Both ends cut at 30 degrees off square, ends are parallel)
2 - 1x2 @ 6 1/4" (Both ends BEVELED at 30 degrees off square, ends are parallel)

Thanks for any help here, I am a little confused!
