Draw any line segment, say $\overline{\mathrm{A}\mathrm{B}}$. Take any point C lying in between $\mathrm{A}$ and $\mathrm{B}$. Measure the lengths of $\mathrm{A}\mathrm{B},\mathrm{}\mathrm{B}\mathrm{C}$ and $\mathrm{A}\mathrm{C}$. Is $\mathrm{A}\mathrm{B}=\mathrm{A}\mathrm{C}+\mathrm{C}\mathrm{B}$?
[Note: If $\mathrm{A},\mathrm{B},\mathrm{C}$ are any three points on a line such that $\mathrm{A}\mathrm{C}+\mathrm{C}\mathrm{B}=\mathrm{A}\mathrm{B}$, then we can be sure that $\mathrm{C}$ lies between $\mathrm{A}$ and $\mathrm{B}$.]
