Class 6 Maths Basic Geometrical Ideas Ray

Ray

A ray can be defined as a straight line that starts from a point and extends indefinitely in one direction. The starting point that is fixed at one end is termed as vertex of a ray. Ray is also one-dimensional entity as we can move endlessly in one direction only.

Labelling a ray is not as simple as a point or a line. Let us take an example, we have a battery-operated torch on one end of the road and light from the torch (called as line segment) is travelling in straight line towards the other direction. Since, we do not know the end of that light we can say that this line segment from a fixed source is a ray
