Segment Congruence Postulate
If two segments have the same length as measured by a fair ruler, then the segments are congruent (≅). Also, if two segments are congruent, then they have the same length as measured by a fair ruler.
The Segment Congruence Postulate, also known as the Segment Addition Postulate, states that for any line segment AB, if there exists a point C between A and B, then the length of segment AB is equal to the sum of the lengths of segment AC and segment CB. This can be represented mathematically as AB = AC + CB.
In simpler terms, this postulate means that if you divide a line segment into two parts, the sum of the lengths of those parts is equal to the length of the original segment. For example, if a line segment AB has a length of 6 units and there exists a point C that divides it into two segments, AC and CB, such that AC has a length of 2 units and CB has a length of 4 units, then AB = AC + CB which is equal to 2 + 4 = 6 units.
The Segment Congruence Postulate is important in geometry because it allows us to make precise mathematical statements about the equality of lengths of line segments. We can use this postulate to prove various theorems and solve problems related to geometric figures such as triangles, quadrilaterals, and circles, where the lengths of line segments play a crucial role.
