Segment Addition Postulate

When we are talking about points we use capital letters like A, B and C.

When we are talking about a length of a segment we would use the 2 end points to name it such as line segment AB would just be written AB.

We can find the length of a segment on a number line by finding the distance between 2 points.

We can also compare lengths on a number line.

True

Now if we know the whole and a part, can you find the other part?

Now, if you can do it with numbers can you do it with ALGEBRA???

To check your work, add the segments together to see if it checks.
