Question

What is the difference between a line and a ray?

Answer 1

we have the following:

Ray:

1. Ray has a starting point and another near the point of the row.

2. You have a starting point but no other ending points. So its length cannot be measured.

3. The symbol for ray is:

`\rightarrow`

Line:

1. There are no end points on a line.

2. There are no end points, so length of a line cannot be measured.

3. The symbol of a line is:

`\leftrightarrow`
