Ray is longer than half line
WebA half-line is just a set of the form a + t b for t ≥ 0, in a vector space over the reals. In the plane this just amounts to lines that are "cut off", i.e. have an endpoint, but then extend towards infinity. Say { ( x, 0): x ≥ 0 }, the positive x-axis, or the negative one too, is an …
