Line–line intersection

So you know how sometimes when you draw a line with your crayon or pencil, another person might draw a line too, right? Sometimes those lines might cross each other!

That's what line-line intersection means. It's when two lines (like those drawn with crayons or on a piece of paper) meet or cross each other.

Think about it like a game of "X marks the spot." When two lines cross each other, they create a little "X" where they meet.

Mathematicians and scientists use special formulas and equations to figure out exactly where those lines will cross, but for now, just know that line-line intersection is when two lines cross each other.
