a)

b)

a)
To find:
The length of segment EF.
Approach:
Measuring line segments:
The instrument used to measure a line segment is a scaled straightedge such as a ruler, a yardstick, or a meter stick.
When we express the length of a line segment, we do not write the bar on top of the name of line segment. Suppose the length of line segment
To find the length of line segment using a ruler:
1. Place the ruler so that “
2. Read the length of line segment by reading the number at the remaining endpoint of the line segment.
When “
c)
To find:
The length of segment GH.
