1. sum and difference of line segments and their properties

1. ruler drawing: sum and use of line segments

.

2. Ruler drawing: the difference of line segments

Draw a straight line $AF$ with a ruler, intercept the line segment $AB=a$ with a compass on the straight line $AF$, and intercept the line segment $BD=b$ with a compass on the $AB$, then the line segment $AD$ is the difference between $a$ and $b$. Remember.

3. Properties of line segments

(1) Distance between two points

The length of a line segment connecting two points is called the distance between these two points. It is the length of the line segment, not the quantity.

(2) The shortest line segment

Of all the connecting lines of two points, the line segment is the shortest, which is briefly defined as the shortest line segment between two points.

related examples of sum and difference of line segments

if $C$, $D$ are two points on line segment $AB$, and $D$ is the midpoint of line segment $AC$, if $AB=1$ and $BC=4$, the length of $AD$ is equal to _ _ _

Because $D$ is the midpoint of the line segment $AC$, $AD= rac{1}{2}AC=3$. So choose B.
