Answer 2

Answer:

Central Angle is the angle formed by two arms with the center of a circle as the vertex.

Step-by-step explanation:

The two arms form two radii of the circle intersecting the arc of the circle at different points. Central angle helps to divide a circle into sectors. A slice of pizza is a good example of central angle. A pie chart is made up of a number of sectors and helps to represent different quantities. A protractor is a simple example of a sector with a central angle of 180º. Central angle can also be defined as the angle formed by an arc of the circle at the center of the circle.
