Question

Draw a line with 3 distinct points on it. Label each with a different letter. How many different
rays can you name using only the three given points?

Answer 1

You can name 6 different rays using the three given points.

For example, if the three points are labeled A, B, and C, the rays are:

1. Ray AB
2. Ray AC
3. Ray BA
4. Ray BC
5. Ray CA
6. Ray CB

Note that even though the first three rays appear to be duplicates of the last three, they are considered distinct because the order of the letters matters when naming rays.
