Segment addition postulate
In geometry, the segment addition postulate states that given two points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC. This is related to the triangle inequality, which states that AB + BC AC with equality if and only if A, B, and C are collinear (on the same line).

What is the Segment Addition Postulate?
The segment addition postulate, or line segment addition postulate, is a property of line segments. It is used to determine whether or not a point lies on a line segment. In other words, it is used to determine whether three points are collinear, which means that they all lie on the same line.
Segment Addition Postulate Examples
Here are some more examples of how to use the segment addition postulate. Remember, a point B lies on a line segment AC if and only if |AB| + |BC| = |AC|.
Additional Examples
In the following examples, students will use the Segment Addition Postulate to determine the lengths of various parts of a line segment. After completing the first few examples, students will attempt a more challenging example which uses the Segment Addition Postulate more than one time.
Examples
1) Point B lies on line segment AC. AB is of length 12 and BC is of length 20. How long is the entire segment AC?
Solutions
1) Since B lies on the segment AC, we know from the Segment Addition Postulate that AB + BC = AC. So we have 12 + 20 = 32.
Segment Addition Postulate Definition
The segment addition postulate states that if a line segment has two endpoints, A and C, a third point B lies somewhere on the line segment AC if and only if this equation AB + BC = AC is satisfied. Look at the image given below to have a better understanding of this postulate.
Segment Addition Postulate Formula
If the end-points of a line segment are denoted as A and C, and there lies a point B on the line segment, then the segment addition postulate formula is given as AB + BC = AC. If there are two points B and D on the segment, we will have the formula as AB+BD+DC = AC.
Segment Addition Postulate Examples
Example 1: In the given figure, if B is the mid-point of line segment AC, find the length of segment AC.
FAQs on Segment Addition Postulate
The segment addition postulate in geometry is the axiom which states that a line segment divided into smaller pieces is the sum of the lengths of all those smaller segments. So, if we have three collinear points A, B, and C on segment AC, it means AB + BC = AC. It is a mathematical fact that can be accepted without proof.

What is a Segment?
It is necessary first to define the term line. It represents an infinite direction or set of points that extend in both directions. Since geometry is a science that studies lines, you can add an arrow at the end to draw lines to show its infinity. If we want to offer a line segment when drawing lines, you can put two dots instead of arrows.
Segment Bisector – Definition and types
In fact, the human eye can quickly and accurately visually divide things into two equal, symmetrical parts. When we talk about the bisector of a line segment, it denotes the intersection of the segment into two halves or pieces. A bisector can be in the form of a point, direction, ray, or segment line that will intersect another segment line.
Segment Addition Postulate – Definition
If you have some two points, A and C, positioned on a line segment, you can place the third point B on the line segment between points A and C. You can do it only if the sum of the distances of points A and B and the distance of points B and C is equal to the total length from point A to point C.
Segment Addition Postulate Formula
Based on the definition of the postulate, it is effortless to formulate a definition that follows the theoretical background. This is the basic addition operation, and in this case, it looks like this:
Segment vs Angle Addition Postulate
For the sake of comparison, we will take the angle addition postulate as an example. The definition of this one tells you that when you place two or more angles next to each other in such a way that their vertices are common, the sum of these adjacent angles is equal to the total sum of the angles.
