Line Segment Measurement
A line segment is a fixed portion of a line. This makes it possible to measure a line segment.
Measuring line segments can be done by:
1) Comparing by observation.
Just by looking at them we can tell which one is longer.
2) Comparison by Tracing.
To compare AB and CD, we use a tracing paper, trace CD and place the traced segment on AB.
3) Comparison using ruler and divider.
Use the ruler, mark the measurements and compare the value.
