Why are lines AC and RS skew lines?

A
They lie in the same plane but will never intersect.
B
They lie in different planes and will be parallel if a plane is drawn to contain both lines.
C
They lie in different planes and will never intersect.
D
They lie in different planes but will intersect if a plane is drawn to contain both lines.

B
converse of the same side interior angles theorem
C
same side interior angles theorem
D
converse of the alternate interior angles theorem

A
They are not parallel because their slopes are negative reciprocals.
B
They are not parallel because their slopes are not equal.
C
They are parallel because their slopes are negative reciprocals.
D
They are parallel because their slopes are equal.

Which diagram shows lines that must be parallel lines cut by a transversal?

A
Image with description Two left-to-right lines are crossed by a vertical transversal. At the upper intersection, the angle below the line and to the right of the transversal is labeled 91 degrees. At the lower intersection, the angle above the line and to the right of the transversal is labeled 89 degrees.
B
Image with description Two left-to-right lines are crossed by a vertical transversal. At the upper intersection, the angle above the line and to the right of the transversal is labeled 89 degrees, and the angle below the line and to the right of the transversal is labeled 91 degrees. No angle measure is shown at the lower intersection.
C
