A ray starts at a point and extends infinitely in one direction, like AB. Unlike a line segment, a ray has only one endpoint and no fixed length, representing partial infinity.
Class 6 Mathematics Chapter 2 Lines and Angles question answer
Class 6 NCERT Ganita Prakash Chapter 2 Lines and Angles
A ray is a portion of a line that starts at an endpoint and extends infinitely in one direction. For example, ray AB starts at A and extends beyond B. Unlike a line segment, which has two fixed endpoints, a ray has only one endpoint and no measurable length. Examples include a torch’s beam or sunlight rays. Rays are essential for constructing angles and analyzing geometry’s directional properties.
