Interactive rulers are used to determine the length of a line segment.
The question is incomplete, as the image of the interactive ruler is not given. However, I will give a general explanation on how to determine the length of a line segment.
To determine the length of segment AB from the interactive ruler (see attachment), we do the following
- Note the location of point A; A = 1 mm
- Repeat the same for point B; B = 3.5 mm
- The length of segment AB is the absolute difference of A and B.
So, we have:
[tex]AB = |A - B|[/tex]
[tex]AB = |1mm - 3.5mm|[/tex]
[tex]AB = |- 2.5mm|[/tex]
Remove absolute brackets
[tex]AB = 2.5mm[/tex]
Hence, segment AB is 2.5 mm; using the assumed values.
