Reflection in the Y axis (geometry)

So a trick for things like these is let’s start with the axis that’s being reflected, it’s the Y. so something I learned is that for example look at point E, E is 1 away from the y axis. so to reflect it you go one away on the other side.

E(1,0) D(5,-2) G(5,-3) F(2,-5)

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 : )
