Find the straight lines that pass through the point 𝐵.
In this figure, we can see that there are a few different line segments that include the point 𝐵. The line segments 𝐵𝐴, 𝐵𝑀, and 𝐵𝐶 are all line segments that have an endpoint at 𝐵. We know that there exist lines through any two points in space, which means that there will be three lines through point 𝐵. They are the line 𝐵𝐴, the line 𝐵𝑀, and the line 𝐵𝐶. Of course, it’s worth noting that there are an infinite number of lines passing through any point. But in this figure, by using the given line segments, we can say that there are only three lines. We can therefore give our answer using the line notation that the lines which pass through the point 𝐵 are 𝐵𝐴, 𝐵𝑀, and 𝐵𝐶.
