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 Is for Answers that Spencer did not hurt her. After telling them about what happened that night, all the girls are attacked by what appears to be "A" and they run up to the roof. (Ian Harding) comes up just as “A” reaches them and claims to know who “A” is but “A” does not seem to care. He and “A” struggle for the gun, which is dropped in the struggle. Hanna picks it up and threatens the masked person at gunpoint to take off the mask. “A” pretends to reach for the mask, then jumps over to the next building and leaves
