If a line is tangent to a circle, then the measure of the angle from the center is always ______ degrees. Therefore, that line is ______________ to the radius.
Tangent Tangent Angle Theorem
Tangent-Tangent Angle Theorem
An angle created by two tangent lines meeting at the same external point and its associated central angle measure add up to _________ degrees. Therefore, the angles are _____________.
