Question

An angle in a circle whose vertex is at the center of the circle is called a ______ angle.

ANSWER:
CENTRAL

Answer 1

An angle in a circle whose vertex is at the center of the circle is called a central angle.

Explanation:

The vertex of an angle is the point about which an angle is measured. For example in angle ABC, point B is the vertex.

If all the points on the figure are equidistant from the center, then the figure is called a circle.

An angle with endpoints located on a circle's circumference and vertex located at the circle's center is known as central angle.

Therefore the angle in a circle whose vertex is at the center of the circle is called a central angle.

In the below figure O is the center of the circle and vertex of the angle AOB an dangle AOB known as central angle.

Answer 2

Answer: An angle in a circle whose vertex is at the center of the circle is called a Central angle.

Explanation:

• A central angle is an angle that obtains when two radii are drawn from the center of a circle out to its circumference.

A central angle's vertex will always be the center point of a circle.

Therefore, An angle in a circle whose vertex is at the center of the circle is called a Central angle.
