3. Through a given Point, without a given Line, a Line may be drawn such that the two Lines are equally inclined to any transversal. |
4. A Pair of Lines, which are equally inclined to a certain transversal, are so to any transversal. |
5. A Pair of Lines, which are unequally inclined to a certain transversal, are so to any transversal. |
6. A Pair of separational Lines are equidistantial from each other. |
∗7. A Pair of Lines, of which one has two points on the same side of, and not equidistant from, the other, are intersectional. |
