In general, if {eq}\angle{CAB} {/eq} is a central angle and {eq}\angle{CDB} {/eq} is an inscribed angle, we have the following formula: $$m\angle{CDB}=\frac{1}{2}m\angle{CAB} $$ Find the Central Angles and Inscribed Angles of a Circle: Finding Central Angle from...
The central angle of a circle that intercepts an arc of length equal to the radius (Fig. 5) is said to have a measure of one radian. The familiar formula for the circumference of a circle tells us that there will be 2π radians in a full circle of 360°, hence that π radians =...
