## Task 4

When measuring two line segments, Ines finds that the segment $\overline{A B}=5 \mathrm{~cm}$ and the segment $\overline{B C}=3$ $\mathrm{cm}$ long.

Udo also measures and obtains: $\overline{A B}=50 \mathrm{~mm}$ and $\overline{B C}=30 \mathrm{~mm}$.

Is there a difference between the measured segments?
Ines and Udo have measured the same distances.
