1. TODAY IN GEOMETRY…  WARM UP: SRF and Rationalizing the Denominator  Learning Target: 6.3 Use properties of similar polygons to solve proportions.  Independent Practice  Ch.6 Quiz – NEXT WEEK!

3. SIMILAR POLYGONS: two polygons that have congruent corresponding angles and side lengths are proportional.

4. SCALE FACTOR: the ratio of the lengths of two corresponding sides of two similar polygons. Check that the ratios of the corresponding side lengths are equal.

5. EXAMPLE: Determine whether the polygons are similar. If they are, write a similarity statement and find the scale factor.

6. PRACTICE: Determine whether the polygons are similar. If they are, write a similarity statement, find the scale factor and solve for x.

8. PRACTICE: The scale factor of Figure 1 to Figure 2 is 7:10. Complete the table. A A B B CC D D E E 1 2
