Question

e. Central angle = ??
​

Answer 1

Answer:

A central angle is an angle whose apex (vertex) is the center O of a circle and whose legs (sides) are radii intersecting the circle in two distinct points A and B. .The central angle is also known as the arc's angular distance. The size of a central angle Θ is 0° < Θ < 360° or 0 < Θ < 2π (radians).

Step-by-step explanation:

Divide the length of the curve with the radius, to get the central angle. The central angle of a circle is measured in radian measure and sexagesimal measure. The unit of radian measure is radians and the unit of sexagesimal measure is degrees.
