Define concurrent lines and intersection lines.

Hint: In this question, we need to define concurrent lines and intersection lines. First, we will understand the meaning of concurrent lines and intersecting lines and we will also draw diagrams for each of them for better understanding.

Complete step by step answer:
Here we need to define concurrent lines and intersection lines.
Let us first understand the meaning of concurrent lines along with a diagram.
When two or more lines pass through a single point they are concurrent with each other and they are called concurrent lines. The point at which all the lines meet is called the point of concurrency. Let us look at the figure below:


Here lines l, m, and n are all crossing point o. Hence all these lines are concurrent with each other and thus are concurrent lines. Point o is called the point of concurrency.
Now let us understand the meaning of intersecting lines along with a diagram.
When two lines share exactly one common point then these lines are called intersecting lines. We can also say that two lines that cut each other at a single point are called intersection lines. The point which is common to both lines is called the point of intersection. Let us look at the figure below:

Here both lines l and m share exactly one point which is o. Thus these lines are intersection lines. Point o is called the point of intersection.
Note:
 Students should note the difference between concurrent lines and intersection lines. When two lines cut each other we say they are intersecting lines but when more than two lines cut each other we say that they are concurrent lines.
