Question

For 13-16, use geometric notation to explain each picture in as much detail as possible. I know it’s limited to one question so please do the purple figure (second one)

Answer 1

25) Figure 25 consists of a segment (AB) and a ray (AC) which intersects at point A.

Such points, segment, and ray are on a plane that we will call ABC because it contains points A, B, and C.

Therefore, using the usual notation,

`\begin{gathered} \bar{AB}\rightarrow\text{ segment AB} \\ \vec{AC}\rightarrow\text{ ray AC} \\ ABC\rightarrow\text{ plane that contains A, B, and C} \end{gathered}`

Thus, the whole figure can be described by the expression below

`\begin{gathered} \vec{AC},\bar{AB}\in ABC \\ or\text{ even} \\ \vec{AC}\cup\bar{AB}\in ABC \end{gathered}`
