which figure shows a central angle? submit
Answer
Explanation:
Step1: Recall central - angle definition
A central angle of a circle is an angle whose vertex is at the center of the circle and whose sides are radii of the circle.
Step2: Analyze each figure
In the first figure, the line is a chord (not a central - angle). In the second figure, the vertex of the angle is at the center of the circle and the sides are radii, so it is a central angle. In the third figure, it shows a sector but not the central angle itself. In the fourth figure, it is just a radius, not a central angle.
Answer:
The second figure.
