Explanation

**Definition:**

Concurrent:

A number of lines are concurrent if they have exactly one point in common.

Two or more lines in a plane that have a single point in common are known as concurrent lines. When exactly two lines have a point in common, we generally describe them as intersecting lines rather than concurrent lines.

**Given:**

**Calculation:**

By the above definition,

In given figure, the three lines are not concurrent even though any pair of lines (such as
