Illustrated definition of Ray: A part of a line with a start point but no end point (it goes to infinity) Try moving...
A ray starts at a given point and goes off in a certain direction forever, to infinity. The point where the ray starts is called (confusingly) the endpoint. On its way to infinity it may pass through one or more other points.
Jan 11, 2023 · How to draw a ray; Symbol and Label; Examples; Ray definition in geometry. A ray is part of a line. Rays have a fixed starting point and no end point. A ray extends in only one direction infinitely. The ray's starting point and another point along the ray are used to name the ray in geometry.
Definition: A line which starts at a point with given coordinates, and goes off in a particular direction to infinity, possibly through a second point. Try this Adjust the ray below by dragging an orange dot and see how the ray AB behaves. You can also drag the origin point at (0,0).
Definition. A ray (in geometry) is a line characterized by a defined starting point (the terminus) with infinite length in only one particular direction (no ending point). 00:00.
Aug 22, 2024 · In geometry, a ray is usually taken as a half-infinite line (also known as a half-line) with one of the two points A and B taken to be at infinity. There are several definitions of a ray. When viewed as a vector, a ray is a vector AB^-> from a point A to a point B.
