What is a ray in Geometry
That is an example. Hope it helps!
A ray is just a straight line.
.
A line with a single start poit (starts at a point or coordinate and does not extend farther in that direction) that extends infinitely in the one direction ( the other side does not have an end poit so it continues forever).
A ray is a line that goes only one direction
