In the book "The Elements of Geometry," written by the ancient Greek mathematician Euclid, he created a comprehensive model showing how all properties and theorems of geometry can be logically studied. The following five axioms detail Euclid's model.

- It is always possible to draw a straight line between any two points.
- Any straight line can be extended indefinitely.
- It is always possible to draw a circle with any given point as the center and any given radius.
- All right angles are equal.
- For any given line and a given point not lying on that line, there is exactly one line passing through that point that does not meet the given line.
