The angle you are referring to is called a "central angle." A central angle is formed when two radii (lines connecting the center of the circle to any point on its circumference) of a circle create an angle. The vertex of the central angle is the center of the circle.

To find the word that fits this definition, you can try searching for "angle with vertex at the center of a circle" or "angle formed by two radii of a circle." Additionally, you can consult math textbooks, online math resources, or use mathematical glossaries to find the specific term "central angle."

Remember, a central angle is just one type of angle formed within a circle. Other types of angles include inscribed angles, tangent angles, and intersecting arcs.
