Question

Name the rays given in this picture:

Answer 1

- Hint: First of all, choose the initial point and find a ray where it has an infinite length of terminal or end point. So, use this concept to reach the solution of the given problem.


Complete step-by-step solution -

Definition of Ray: A portion of a line which starts at a point and goes off in a particular direction to infinity.
So, the ray has an initial point, it doesn’t have a terminal point or end point.
In the given figure,
\[\overrightarrow {TA} \] is a ray with initial point T.
\[\overrightarrow {TN} \] is a ray with initial point T.
\[\overrightarrow {TB} \] is a ray with initial point T.
Thus, the rays in the given figure are \[\overrightarrow {TA} ,\overrightarrow {TN} \& \overrightarrow {TB} \].

Note: A ray is one-dimensional It has zero width. The length of a ray is infinity or we can’t measure its length as it goes continuously along a particular direction. \[\overrightarrow {AB} \] can be read as ray AB where the arrow indicates that A is the point where ray starts.
