When segments intersect outside a circle what is the relationship between the angle of intersection and the intercepted arcs?

When two segments intersect outside a circle, the measure of the angle formed by the intersecting segments is equal to half the difference of the measures of the intercepted arcs. Specifically, if the angle is formed by segments that intersect outside the circle, the angle's measure is calculated as (Arc 1 - Arc 2)/2, where Arc 1 and Arc 2 are the measures of the arcs intercepted by the angle on the circle. This relationship helps in solving various geometric problems involving circles and angles.
