Always sometimes or never
Two opposite rays______form a line
Always.
To understand why two opposite rays always form a line, let's break it down:
- Rays are lines that have a starting point but extend infinitely in one direction.
- Opposite rays are two rays that share the same starting point, but extend in opposite directions.
- When two opposite rays are combined, they form a straight line.
To visualize this, imagine drawing two rays with the same starting point A. Let's call them Ray AB and Ray AC.
- Ray AB extends from A towards one direction, let's say to point B.
- Ray AC extends from A towards the opposite direction, let's say to point C.
When we combine Ray AB and Ray AC, they form a line. This line passes through point A (the common starting point) and also extends infinitely in both directions.
So, two opposite rays always form a line.
