## What shape is described by 3 points where 2 lines meet?

I was listening to Tessellate by alt-J yesterday and thinking about the line “triangles are my favorite shape: three points where two lines meet.” Triangles of course involve three lines, but what if there were only two?

**What is the point where two lines meet is called?**

Intersecting lines – Definition with Examples When two or more lines cross each other in a plane, they are called intersecting lines. The intersecting lines share a common point, which exists on all the intersecting lines, and is called the point of intersection.

**What point is shared by two lines?**

When two lines share exactly one common point, they are called the intersecting lines. The intersecting lines share a common point. And, this common point that exists on all intersecting lines is called the point of intersection.

### What are three lines that intersect in three points?

We will learn how to find the condition of concurrency of three straight lines. Three straight lines are said to be concurrent if they passes through a point i.e., they meet at a point.

**What is the intersection of two planes?**

The intersection of two planes is a line. If the planes do not intersect, they are parallel. They cannot intersect at only one point because planes are infinite. Furthermore, they cannot intersect over more than one line because planes are flat.

**What are two lines that never meet?**

Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect.

## Where do two planes meet?

The intersection of two planes is a line. If the planes do not intersect, they are parallel.

**What are these lines that meet at a single point?**

Straight lines that cross each other at some point are called intersecting lines. These lines will intersect at one point only over their entire length. There is no symbol to use when naming intersecting lines.
