1. Segments of Tangents, Secants and Chords

2. Segments Formed by Tangents Theorem • If two segments are tangent to a circle from the same external point, then the segments are congruent

4. Segments Formed by Secants Theorem • If two secants intersect outside a circle, the product of the lengths of one secant segment and its external segment equals the product of the lengths of the other secant segment and its external segment. • (whole x outside = whole x outside)

6. Segments Formed by Secants Theorem • If a secant and a tangent intersect outside a circle, then the product of the lengths of one secant segment and its external segment equals the length of the tangent segment squared. • (whole x outside = tangent squared)

8. Segments Formed by Intersecting Chords Theorem • If two chords intersect inside a circle, then the product of the lengths of the segments of one chord equals the product of the lengths of the segments of the other chord.
