Question

which statements are true regarding the diagram? check all that apply. cb is contained on line n. ac is contained on line m. ray bc is the same as ray cb. ray ad is the same as ray ac. ∠ead is created from ea and da. ∠ecb is created from ec and cb.

Explanation:

Step1: Analyze each option

• For the first option: $\overrightarrow{CB}$ is on line $n$.
• For the second option: $\overrightarrow{AC}$ is on line $n$, not line $m$.
• For the third option: Ray $BC$ and ray $CB$ have different starting points.
• For the fourth option: Ray $AD$ and ray $AC$ have the same starting point $A$ and extend in the same direction.
• For the fifth option: $\angle EAD$ is formed by $\overrightarrow{EA}$ and $\overrightarrow{DA}$.
• For the sixth option: $\angle ECB$ is formed by $\overrightarrow{EC}$ and $\overrightarrow{CB}$.

Answer:

$\overrightarrow{CB}$ is contained on line $n$, Ray $AD$ is the same as ray $AC$, $\angle EAD$ is formed from $\overrightarrow{EA}$ and $\overrightarrow{DA}$, $\angle ECB$ is formed from $\overrightarrow{EC}$ and $\overrightarrow{CB}$
