Given the intercepted arc or central angle, to find the inscribed angle, divide the measure by two. This is the value of the inscribed angle. What is the formula for the inscribed angle? Consider an inscribed angle measuring x and the corresponding central angle or intercepted arc of measure...
Another term that must also be clear is the intercepted arc. The intercepted arc is the part of the circle between the intersection points of the sides of the angle and the circle. In the previous example, arc DT is the intercepted arc of the inscribed angle ∠DRT while arc SB is the ...
Steps for Using the Inscribed Angle Theorem with Chords & Tangents of a Circle Step 1:From the given figure, identify the angle formed by the tangent line and chord. Identify the intercepted arc and its measure. Step 2:Divide the measure of the intercepted arc identified in st...

Angle ACB is an inscribed angle and has vertex C on the circle. You decided to simply walk back from B to your starting point A. The path you would follow is the intercepted arc - the arc where the sides of the angle intersect the circle. The red arc, AB, is the intercepted arc...
