Question

The angle between two ray is $0^o.$ Choose the correct option(s) regarding the two rays.

• A. The two rays intersect at a single point.
• B. The two rays may intersect at infinitely many points.
• C. They can be parallel to each other.
• D. They are opposite to each other.

Answer 1

Answer: (B), (C)

They can be parallel to each other.

Angle between two parallel rays is $0^o.$
By overlapping one ray over the other, we see that the angle between them is zero degree.

They will intersect at infinite number of points.

When these two rays are opposite two each other, they form ${180}^o$ angle

Hence, the correct options are (b) and (c).
