How do you name a ray, and what is the correct notation for a ray starting at U and passing through V?

You're on a roll — To name a ray, you must start with its endpoint and then list another point on the ray, with an arrow symbol above pointing in the direction of extension. Step 1: Identify the endpoint of the ray. The ray in the image starts at point U. This is its endpoint. Step 2: Identify another point on the ray. The ray passes through point V. Step 3: Determine the direction of the ray. The ray extends infinitely from U, through V, and beyond V. Step 4: Choose the correct notation. The notation for a ray starts with the endpoint, followed by another point on the ray, with a single-headed arrow above pointing to the right. Therefore, the ray starting at U and passing through V is written as UV. Let's check the given options: UV: This represents a line segment between U and V. UV: This represents a ray starting at U and extending through V. This matches the diagram. VU: This represents a ray starting at V and extending through U. This is incorrect as the ray starts at U. UV: This represents a line passing through U and V, extending infinitely in both directions. The correct way to write the name of this ray is UV. The final answer is UV Just one more to go today!
