10.6 Segment Lengths in Circles 5/11/10
Finding the Lengths of Chords • When two chords intersect in the interior of a circle, each chord is divided into two segments which are called segments of a chord.
Theorem 10.14 EA • EB = EC • ED
Chords ST and PQ intersect inside the circle. Find the value of x. Ex. 1: Finding Segment Lengths
In the figure shown, PS is called a tangent segment because it is tangent to the circle at an end point. Tangents and Secants
