The arrow over the two letters indicates it is a ray, and the arrow direction indicates that A is the point where the ray starts. There is a shorthand way of writing this: This is read as “ ray AB”. Recall that points are usually labelled with single upper-case (capital) letters. Video quote: And the line is containing these three points that i'm giving names to l m and p even though we know a line contains infinite many points. We can mark this point as a and mark a point B somewhere on the array. Video quote: In one direction just like four lines even rays can be drawn in different ways. 3a : a stream of material particles traveling in the same line (as in radioactive phenomena) b : a single particle of such a stream. 2 : a beam of radiant energy (as light) of small cross section. With an arrowhead on each end line segment that's part of aġ : one of the lines of light that appear to radiate from a bright object. This line it continues in both directions. Video quote: Point it's an exact location in space it's like a dot. So, together a pair of opposite rays always forms a straight line. Can opposite rays form a line?Ī pair of opposite rays are two rays that have the ‘same endpoint and extend in opposite directions. A line segment continues in both directions, a ray only continues in one direction. A line segments connects to itself forming a shape, a ray does not. What is the opposite ray?Ī ray has two end points whereas a line segment only has one. An example of a ray is a sun ray in space the sun is the endpoint, and the ray of light continues on indefinitely. In geometry, a ray is a line with a single endpoint (or point of origin) that extends infinitely in one direction.
