Question

1. Refer to the following line m:
b. Name two rays on m that have endpoint B.
d. Find a simpler name for the intersection of rays BA and AC

the line m has points a b and c going on across like that on the line
would the answer be ba and bc?
what would the answer to d be?

Answer 1

I don't understand where or what the rays BA and AC are. If you are talking only about a line m with points on it, what is there to intersect?

Why do you switch from lower case ba and bc to capitals BA and AC?

Answer 2

<---------------->
A B C

Thank you for responding. This is what the line looks like but with points where the a b and c are. i thought for finding rays you would use ba as one and bc for the other since a ray is an arrow in one direction and a point at the other? sorry i didn't mean to change to from lower case to capitals. I don't understand about the intersection either that's why i posted so someone could help explain. it wouldn't be vertex would it?

Answer 3

Endpoint apparently means one of the two ends of a line.

BA (or AB) and BC (or CB) both have A as endpoints.

The intersection (common endpoint) of BA and AC is A, but the lines are parallel, so they coincide over the whole length from A to B. You could call A a vertex, but there is no triangle in this case.

Answer 4

I appreciate you taking the time out to answer again but I'm even more confused now. How do I get B as an endpoint and are you saying that the answer to d would be common endpoint? Thanks.
