What is a central angle and what is the relationship of the measures of the central angle and the intercepted arc?
oh maybe theta=l/r where l is length of arc
r is radius and theta in radian
|dw:1335854430874:dw| The angle subtended by an arc at the center of a circle is the Central Angle.
\[\text{Here L is the arc length}\] \[\text{Here r is the radius of the circle}\] \[\text{Here}\ \theta\ \text{is the central angle}\] \[\text{Relation between central angle and arc length:}\] \[\Huge L=r \times \theta\]
@Abbie23 Do you understand this?
