Question

¿qué representa aob en el círculo de la imagen? * (1 point)
radio
diámetro
punto central
ángulo central

Explanation:

In a circle, a central angle is an angle whose vertex is at the center of the circle (point \(O\) in this case) and whose sides are radii of the circle (\(OA\) and \(OB\)). A radio (radius) is a single line - segment from the center to the circumference (e.g., \(OA\) or \(OB\) alone). A diametro (diameter) is a line - segment passing through the center with endpoints on the circumference. A punto central (central point) is just the center point (\(O\) itself, not an angle). Since \(AOB\) is an angle with vertex at the center \(O\) and sides as radii, it fits the definition of a central angle.

Answer:

Ángulo central
