WebJun 5, 2024 · Using the central angle theorem, the measure of the intercepted arc on Earth is: 42° What is the Central Angle Theorem? Based on the central angle theorem, the measure of a central angle equals the measure of the intercepted arc. Half of the measure of the central angle = 180 - 90 - 138/2 = 21° Central angle = 42° Central angle = intercepted arc WebIntercepted arc: Corresponding to an angle, this is the portion of the circle that lies in the interior of the angle together with the endpoints of the arc. In Figure 1, ∠ ABC is an inscribed angle and is its intercepted arc. Figure 1 …

That is, m ∠ A B C = 1 2 m ∠ A O C. This leads to the corollary that in a circle any two inscribed angles with the same intercepted arcs are congruent. Here, ∠ A D C ≅ ∠ A B C ≅ ∠ A F C.
