Question

If two lines intersect, then they intersect in exactly _____.

two points

one point

one line

one plane

Answer 1

The would intersect at exactly one point

Answer 2

The correct answer is one point.

Explanation:

In geometry, if two lines cross each other, they will do so at an exact point.

Imagine that the lines are formed by thousands of points located next to each other, which makes us see a line, therefore if they cross, they will do so at a single point that will have a coordinate in (x, y) format.

When the two lines are on the same plane, the following situations may occur:

• if they match they have an unlimited number of points in common

• if they are different but they have the same slope they are parallel and they do not have points in common

• if the above does not happen, they have a single point of intersection.
