Abstract
In this chapter we sum up the well-known properties of an oval and add new ones, in order to have the tools for the various constructions illustrated in Chap. 3 and for the formulas linking the different parameters, derived in Chap. 4. All properties are derived by means of mathematical proofs based on elementary geometry and illustrated with drawings.

Notes
- 1.
Given two tangent circles, any secant line through the tangency point intersects the two circles at points whose connecting lines with the corresponding centres are parallel.
