  1. Chapter 8 Similarity

  2. Section 3Similar Polygons

  3. GOAL 1: Identifying Similar Polygons

  4. Example 1: Writing Similarity Statements Pentagons JKLMN and STUVW are similar. List all the pairs of congruent angles. Write the ratios of the corresponding sides in a statement of proportionality.

  5. Example 2: Comparing Similar Polygons Decide whether the figures are similar. If they are similar, write a similarity statement.

  6. GOAL 2: Using Similar Polygons in Real Life Example 3: Comparing Photographic Enlargements

  7. If two polygons are similar, then the ratio of the lengths of two corresponding sides is called the scale factor. In Example 2 on slide 5, the ratio of 3/2 is the scale factor of WXYZ to PQRS.

  8. Example 4: Using Similar Polygons The rectangular patio around a pool is similar to the pool as shown. Calculate the scale factor of the patio to the pool, and find the ratio of their perimeters.

  9. Example 5: Using Similar Polygons Quadrilateral JKLM is similar to quadrilateral PQRS. Find the value of z.
