If angle aeb has its vertex on the center of a circle and its endpoints on the circle, what is it?

1. Vertex E is the center of the circle, A and B are on the circle.

2. Any angle with these properties (i. E is center, AE and AB are radii) is called a central angle.

3. Check the picture. 

4. An important property of these angles is that the measure of the arc AB = m(AEB)

Just look outside and then you’ll see where the awnser is
