Question

an angle whose vertex is the center of the circle is called​

Answer 1

Answer:

here is the answer

Step-by-step explanation:

Central Angle: An angle whose vertex is the center of a circle. The measure of a central angle is equal to the measure of its intercepted arc. ... Inscribed Angle: An angle whose vertex is a point on a circle and whose sides contain chords.

Answer 2

central angle

An angle whose vertex is at the centre of the circle is called the central angle,θ.

central angle has radian, Initial side, terminal side.

• Radian-It is a measure of the central angle of the circle that intercepts an arc that is equal in length to the radius of the circle.

Formula:

To calculate the central angle of a circle, we need to measure the arc length, the radius of the circle.

$central \\ angle = \frac{arc length*360}{2\pi r} degrees$
