  1. D. N. A. Are the following triangles similar? If yes, state the appropriate triangle similarity theorem. 12.3 2) 1) 15 5 4.1 3) Find the value of x.

  2. In the figure, , and ABC and DCB are right angles. Determine which triangles in the figure are similar. Are Triangles Similar? Lesson 3 Ex1

  3. In the figure, OW = 7, BW = 9, WT = 17.5, and WI = 22.5. Determine which triangles in the figure are similar. A.ΔOBW ~ ΔITW B.ΔOBW ~ ΔWIT C.ΔBOW ~ ΔTIW D.ΔBOW ~ ΔITW Lesson 3 CYP1

  4. ALGEBRAGiven , RS = 4, RQ = x + 3, QT= 2x + 10, UT = 10, find RQ and QT. Parts of Similar Triangles Lesson 3 Ex2

  5. Since because they are alternate interior angles. By AA Similarity, ΔRSQ ~ ΔTUQ. Using the definition of similar polygons, Parts of Similar Triangles Substitution Cross products Lesson 3 Ex2

  6. Parts of Similar Triangles Distributive Property Subtract 8x and 30 from each side. Divide each side by 2. Now find RQ and QT. Answer:RQ = 8; QT = 20 Lesson 3 Ex2

  7. INDIRECT MEASUREMENT On her trip along the East coast, Jennie stops to look at the tallest lighthouse in the U.S. located at Cape Hatteras, North Carolina. At that particular time of day, Jennie measures her shadow to be 1 feet 6 inches in length and the length of the shadow of the lighthouse to be 53 feet 6 inches. Jennie knows that her height is 5 feet 6 inches. What is the height of the Cape Hatteras lighthouse to the nearest foot? A. 196 ft B. 39 ft C. 441 ft D. 89 ft Lesson 3 CYP3

  8. Geometry – Practice Workbook Do not write in the workbook. Write your answers on a separate sheet of paper. Complete: p. 43 #3 – 8 all p. 42 #1 – 5 odd p. 41 # 1 – 15 odd
