How many rays will there be if one straight line is drawn through one point?

Before answering the question, you need to decide on the concepts and definitions used in the assignment.

A straight line is a line that has no beginning or end. It is not limited by anything, it continues endlessly.

And a ray is a line that starts at one point, but does not end.

If you draw a straight line through one point, you get two rays from different sides. They have the same origin. But the first ray goes in one direction along a straight line, and the other goes to the other side.

Answer: two beams.
