Front

What is the significance of the intersection point of two lines?

Back

The intersection point is the location where two lines meet, and it can be used to solve geometric problems.

Front

Can two lines be both parallel and intersecting?

Back

No, two lines cannot be both parallel and intersecting; they are mutually exclusive.
