2. JRLeon Geometry Chapter 6.7 HGSH Arc Length Lesson 6.7 Let’s take another look at the arc measure. EXAMPLE 1 What fraction of its circle is each arc? Solution

3. Arc Length Conjecture The length of an arc equals the JRLeon Geometry Chapter 6.7 HGSH Arc Length Lesson 6.7 Solution C-66 Where C =  d or C = 2  r EXAMPLE 2

4. JRLeon Geometry Chapter 6.7 HGSH Arc Length Lesson 6.7 Solution C =  d or C = 2  r EXAMPLE 3

5. JRLeon Geometry Chapter 6.7 HGSH Arc Length Lesson 6.7 C =  d or C = 2  r Intersecting Secants Conjecture The measure of an angle formed by two secants that intersect outside a circle one-half the difference of the larger intercepted arc measure and the smaller intercepted arc measure.
