It provides pre-drawn diagrams that save time and reduce errors.
Every segment has a length greater than zero.
If a point lies on a segment, the total length is the sum of its parts (
Skipping the logic in Section 4 makes the more complex proofs of Section 5 (Angles) and Section 6 (Triangles) much harder to grasp.
