Central angle and arc

WebSep 15, 2024 · Note: The central angle θ that intercepts an arc is sometimes called the angle subtended by the arc. Example 4.10 Find the area of a sector whose arc is 6 cm in a circle of radius 9 cm. Solution Using s = 6 and r = 9 in Equation for the area A, we get A = 1 2 rs = = 1 2 (9)(6) = 27 cm2 . WebWe set out to prove that the measure of a central angle is double the measure of an inscribed angle when both angles intercept the same arc. We began the proof by establishing three cases. Together, these cases accounted for all possible situations where an inscribed angle and a central angle intercept the same arc.
