definitions of ray in Euclidean, spherical, and elliptic Elliptic geometry. We can look at the right, we can have ray FE, start at F go through E and beyond E, you can have ray FC, start at F go through C and beyond C that is teh same thing as FE ray FE and ray FC are the same as the point E is on ray FC, then finally we have not focussed on point A you may think there is ray AE, but the line does not go beyond E, so it is not a ray, to the top of A there is no other point, so there is no ray there either that is all the rays based on the points specified. A segment in P2 is a set of the form tt Here are some vocabulary words that tell about the geometry concepts that your child. Ray (quantum theory), an equivalence class of state-vectors representing the same stateĪrts and entertainment Music Now students will learn more about the parts that make up these shapes.Ray (optics), an idealized narrow beam of light.Ray (graph theory), an infinite sequence of vertices such that each vertex appears at most once in the sequence and each two consecutive vertices in the sequence are the two endpoints of an edge in the graph.Ray (geometry), half of a line proceeding from an initial point.
