When three or more lines intersect at one point, they are ____________.

concurrent

When three or more lines intersect at one point, they are called concurrent.

When three or more lines intersect at one point, they are called concurrent lines. To understand why, let's break down the term and its concept:

1. Concurrent: In geometry, the term "concurrent" means that multiple lines or objects meet or intersect at a common point.

2. Lines: These are straight objects that extend infinitely in both directions. They can be represented by using line segments or by equations.

So, when we say three or more lines are concurrent, it means that they intersect at a single point. This point of intersection is shared by all the lines involved.
