The answer is radii (plural of radius).

Answer:

the sides of a central angle are two radii of the circle

Explanation:

If we make two lines starting from the center of the circle and take them to the boundary of the circle, they will probably make an angle which is called central angle. Since the single is produced by the two lines starting from center to boundary si these lines are called radius of circle. Simply it means that drawing two radii in a circle anywhere create an angle.
