Question

Lines m and n are parallel lines cut by a transversal l.
Line m is above line n. Angles are labeled 1 to 4 clockwise starting from top left at intersection of lines l & m. Angles are labeled 5 to 8 in the same way for lines l & n.
Which answer gives statements that should be used to prove angles 2
and 7 are supplementary angles

Answer 1

The second option. Angles 2 and 6 are corresponding angles, and 6 and 7 make a linear pair, so 2 and 7 are supplementary.

The first option doesn’t even mention angle 7, the third option doesn’t mention angle 2, and the last option doesn’t mention 7 either.
