  1. Week 5 Warm Up 01.30.12

  2. Similar Polygons Corresponding angles are congruent and the lengths of corresponding sides are proportional. Ex 1 Statement of Proportionality

  3. Ex 2 Similarity Statement ∼ Symbol for Similar

  4. Theorem 8.1 K P L Q R N M S If KLMN ∼ PQRS Then, sides perimeters = = = =

  5. JKLM ∼ QPRS. Find the value of z. Ex 3 = 15z = 6( 10 ) 15z = 60 z = 4

  6. Scale Factor The ratio of the lengths of the corresponding sides. Scale factor of the pool to the patio is: 48ft : 32ft Scale factor = 3 : 2

  7. Ex 4 Statement of Proportionality TUVW ∼ ABCD Scale Factor 5 : 3 Length of TW 30 = 3x 10 = x 180 - 70 m∠TUV 110

  8. Find the value of x. Do: Assignment: Textbook page 461, 10 - 44 Evens and 45 – 50 all.
