Angles and Arcs Cut by Chords, Secants and Tangents NOTES

Hints to help you remember how to solve for missing arcs or angles formed by chords, secants and tangents:

If the angle is _________________________ the circle, ___________________ the arcs.

If the angle is _________________________ the circle, ____________________ the arcs.

The measure of an angle formed by a chord and a tangent is equal to half the measure of the intercepted arc.
