Two lines intersect if they have a point in common.
QA and AB
Practice makes perfect
On the given figure, there are many intersecting lines. This is because any pair of segments ending at the same vertex can be extended to create a pair of intersecting lines. As such, we can choose any two such segments to get our answer. Let's choose segments QA and AB.
Segments QA and AB can be extended to lines QA and AB, which intersect at point A.
