Question

If angle between two rays is $0^o$, then these rays will be

• A. Overlapping each other
• B. Intersecting each other
• C. in opposite direction to each other with common vertex.
• D. Two rays never makes $0^o$ angle

Answer 1

The correct option is A Overlapping each other

We know when one ray overlaps with the other one, the angle between both of them is $0^o$.

When the rays intersect each other, the angle between them is greater than $0^o$.

And when rays are in opposite direction to each other with common vertex, the angle between them is ${180}^o$


Hence, Otion$\left(a\right)$ correct
