When estimating the length of the segment, remember to do it to the nearest tenth of a centimeter. Calculate the distance with the Ruler Postulate.
4.5 centimeters
Practice makes perfect
We want to use a ruler to measure the length of the given segment. To measure the segment, place your ruler under the segment in the exercise in the book. The easiest way to begin is to align the first point with an integer on the ruler.
It appears that the second point aligns with 5.5. To calculate the length of the segment, we will use the Ruler Postulate. It tells us that the distance between two points can by calculated by taking the absolute value of the difference between the two points.
|5.5-1|=|4.5|=4.5
The length of the segment is 4.5 cm. when measured to the nearest tenth of a centimeter.
