Question

What is the relationship between a central angle and its corresponding arc?

Answer 1

This is one of the Geometry definitions you will need to learn. The measure of a central angle of a circle is the same as that of its intercepted arc.

Answer 2

really?

Answer 3

if by intercepted arc you mean arc length, the relationship is
\[s=r\theta\] where s is the length of the arc, r is the radius and theta is the angle

Answer 4

the angle is measured by
\[\theta=\frac{s}{r}\]
