The Segment-Addition Postulate states that if point X is on segment RS, then the sum of the lengths of RX and XS is equal to the length of RS. Therefore, if R-X-S, then the length of segment RS is equal to the sum of the lengths of segment RX and segment XS, which justifies the conclusion that R-X-S is a straight line.
