Question

the ______ of a central angle are two radii of the circle.
a. measurea
b. arcs
c. sides
d. vertices

Explanation:

A central angle is formed by two radii of a circle that meet at the center (the vertex of the angle). The two radii act as the straight sides that form the angle. "Measures" refers to the angle's degree value, "arcs" are curved parts of the circle, and "vertices" are the corner points (only one vertex for a central angle, at the circle's center).

Answer:

C. sides
