1. What is the name of the ray that is opposite of ray BA?
Description of the ray. It's a straight line with the points A B C D all in a row.
A) Ray BD
B) Ray BA
C) Ray CA
D) Ray DA
This doesn't make sense. I thought that CD would be opposite of BA. But I've done some thinking and I think the answer Is BD.
BA has initial point B.
So, you want a ray with initial point B pointing the other way.
That would, of course, be BD.
its bd
BA has initial point B.
So, you want a ray with initial point B pointing the other way.
That would of course be BD.
To determine the name of the ray that is opposite of ray BA, we need to understand that "opposite" in this context refers to the direction rather than the position of the points. To find the answer, you can imagine extending ray BA infinitely in both directions. The opposite ray will start from the same endpoint, which is point A, but will extend in the opposite direction.
In this case, the description states that there is a straight line with points A, B, C, and D in a row. Since the ray mentioned in the options starts from point B, it cannot be opposite of ray BA. Similarly, ray CA and ray DA also start from different points.
Therefore, the correct answer is A) Ray BD, as it starts from point B (same as BA) but extends in the opposite direction.
