Question

which is the endpoint of a ray? point r point s point t point u

Explanation:

Step1: Recall the definition of a ray

A ray has one endpoint and extends infinitely in one direction.

Step2: Analyze each point

• Point R: Not the start of any ray shown.
• Point S: The common starting point for the rays (e.g., ray SR, ray ST, ray SU).
• Point T: Part of a ray (ray ST) but not the endpoint.
• Point U: Part of a ray (ray SU) but not the endpoint.

So, the endpoint of the rays is point S.

Answer:

point S
