If ∠1 ≅ ∠2, which lines are parallel?

Line n and line p are two parallel lines cuts the two parallel lines l and m. Between line n and p there is line q in opposite direction of n and p. Line q is crosses lines l and m. The external angle 1 formed between lines m and n is same as the external angle 2 formed between lines m and p. These angles are called corresponding angles.

A. l || m
B. l || n
C. n || p
D. m || p

A.	l || m

Sailor · Answer

Ok, so it would be option C, because lines N and P do not intersect. Lines Q and M intersect.
