Two parallel lines are intersected by a third line so that angles 1 and 5 are congruent.

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

In which diagram do angles 1 and 2 form a linear pair?

3 lines are shown. One line has points B, A, and E. Another line with points C, A, F intersects that line at point A. Another line comes out of point A and contains point D.
