Tyree is determining the distance of a segment whose endpoints are a(–4, –2) and b(–7, –7).

The answer is b that all that needs to be said lol

Skew lines(segments) are lines(segments) in 3 dimensions that do not intersect the given segment and are not parallel to it.  ae, bf, eg, and fh are your skew segments.  i hope that : )
