Question

  1. draw ray ts (3 pts.) t must clearly be an endpoint 5. marsha made the false statement, “any 4 points are collinear” draw a counterexample that proves that marsha’s statement is not always true? (4 pts.) 6. which of the notations does not represent the drawing below? (4 pts) a. $overleftrightarrow{vj}$ b. $overleftrightarrow{js}$ c. $overleftrightarrow{jv}$

Explanation:

Step1: Recall ray - notation rule

A ray is named with its endpoint first and then another point on the ray. In the given ray with endpoint \(J\) and another point \(V\) on the ray, the correct notations are \(\overrightarrow{JV}\) and \(\overrightarrow{JS}\) (since \(S\) is also on the extended ray).

Step2: Analyze each option

  • Option A: \(\overrightarrow{VJ}\) has \(V\) as the starting - point. But \(V\) is not the endpoint of the given ray, so this notation is incorrect.
  • Option B: \(\overrightarrow{JS}\) is a correct notation as \(J\) is the endpoint and \(S\) is on the ray.
  • Option C: \(\overrightarrow{JV}\) is a correct notation as \(J\) is the endpoint and \(V\) is on the ray.

Answer:

A. \(\overrightarrow{VJ}\)
