Lines k and l are parallel. when lines k and l are cut by the transversals below, an isosceles triangle is formed.

M angle 1 is 40° because 70+70= 140 and subtract 140 with 180 =40

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 : )
