Figure JKLM is a rectangle, so mKJM = mKLM = 90° and KJC MLC.

Angles that are congruent are complementary to the same angle.

Angles that are congruent are supplementary to the same angle.

All angles in a rectangle are right angles.

Complementary angles are always also congruent.

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

2 horizontal lines are intersected by a third line. At the intersection of the first line with the third line, the bottom left angle is 115 degrees. At the intersection of the second line with the third line, the uppercase left angle is 65 degrees.
