Lines ac and rs can best be described as
Intersecting
Parallel
Perpendicular
Skew

Skew (option d).

Step-by-step explanation:

Skew lines are the lines that do not intersect with each other. These lines exist in different planes and hence do not intersect each other and they are also not parallel. For skew lines to exist,  3 -d planes are required.

Here, the lines e and c are skew lines because they do not intersect each other and are lying on different panes. They are also skew line because the planes are co-planer,

Hence, the lines e and c are skew lines.

you cant answer this dummy

step-by-step explanation:

i belive those are the ones that are under 90 degreese.
