Secant line a circle in the Euclidean plane, a line joining two of them would be a 2-secant (or "bisecant") and a line passing through only one of them would be a 1-secant (or "unisecant"). A unisecant in this example need not be a tangent line to the circle. This terminology is often used in incidence geometry and discrete geometry. For instance, the Sylvester–Gallai theorem of incidence geometry states that if points of Euclidean geometry are not collinear then there must exist a 2-secant of them. And the original orchard-planting problem of discrete geometry asks for a bound on the number of
A-not-A question optional here. Here, the verb "watch" is "A", and while the object is included before NEG, it is not included in "A", and is therefore not reduplicated. "A" is reduplicated here. There is some debate amongst speakers as to whether or not 3.d. is grammatical, and Gasde argues that it is. Here, the adjective "good" is "A", and it is reduplicated. The word "ben" is a classifier, which means it is a counter word for the Noun "book." Here, the adjective "good" is "A", but it is not reduplicated. Here, the preposition "at" is "A", and it is reduplicated. Here,
