  1. Chords, Secants, & Tangents (Lengths) 9.3.3.8 Know and apply properties of a circle to solve problems and logically justify results.

  2. Guiding Question: How do I measure intersecting lines in & out of a circle? • Lesson Obj: IWBAT know the properties of a circle and solve problems using them. • Recall • Chords • Secants • Tangents

  3. Guiding Question: How do I measure intersecting lines in & out of a circle? • When 2 chords intersect the pieces multiplied are equal.

  4. Guiding Question: How do I measure intersecting lines in & out of a circle? For 2 secants, you multiply (outside x whole) = (outside x whole) What would the length be for x?

  5. Guiding Question: How do I measure intersecting lines in & out of a circle? Tangent & Secant: (outside x whole) = tangent squared

  6. Guiding Question: How do I measure intersecting lines in & out of a circle? Summary Page: 2 chords: segment x segment = segment x segment 2 secants: outside x whole = outside x whole 1 secant 1 tangent: outside x whole = tangent squared.

  7. Guiding Question: How do I measure intersecting lines in & out of a circle? • Assignment: Worksheets
