When the vertex of an angle is located outside a circle, the measure of the angle is determined by the difference of the measures of the intercepted arcs. Specifically, if the angle intercepts arcs A and B, the angle's measure can be calculated using the formula: (\text{Angle} = \frac{1}{2} (m\overarc{A} - m\overarc{B})), where (m\overarc{A}) and (m\overarc{B}) are the measures of the intercepted arcs. This relationship holds true for both secant and tangent lines that intersect the circle.
