Question

the angle created by ray ox and ray oz is angle
the two rays that create ∠yox are ray ox and ray
the center of the circle is point

Explanation:

Step1: Identify the angle created by ray $OX$ and ray $OZ$

By the definition of an angle (formed by two rays with a common endpoint), the angle with rays $OX$ and $OZ$ and common endpoint $O$ is $\angle ZOX$.

Step2: Identify the ray for $\angle YOX$

An angle $\angle YOX$ has two rays. One is given as $OX$, and from the figure, the other ray with common endpoint $O$ is $OY$.

Step3: Identify the center of the circle

The center of a circle is the fixed point equidistant from all points on the circle. In the given figure, point $O$ is the center as all radii (e.g., $OW$, $OX$ etc.) have $O$ as their endpoint.

Answer:

1. $\angle ZOX$
2. $OY$
3. $O$
