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.
Central Angle An angle in a circle with vertex at the circle's center.
inscribed angle
An angle that's vertex is on the center of the circle.
An angle with its vertex on the center point of the circle.
an angle in an circle whos vertex is on the circle.
No. It's a central angle only if its vertex is at the center of the circle.
