  1. 1. Opener: Please complete the following on your *NEW* opener sheet!!! Please also  leave your homework on your desk for me to check in. The Geometric Mean between 3 and 6 is:  x2= 18 x = 3√2 Using the model above, find the Geometric Mean of each of the following  pairs of numbers: 1.) 3 and 3 2.) 4 and 25 3.) 5 and 30 1
  2. 2. 8.1 Right Triangle Similarity What could you conclude about the three triangles formed when an altitude  was drawn to the hypotenuse of a right triangle? C C A A D B B D A 2
  3. 3. We used the idea of similar triangles to find the answers for # 5.  Today we're  going to use Geometric Mean as a shortcut for this!! C *Middle Altitude (Altitude in 2 smaller triangles) D *Outside Altitudes (Altitudes in big triangle &  1 small triangle) A B 5A.) 5B.) 5C.) 3
  4. 4. Geometric Mean Group Practice: 1. Solve for the variables. 4
  5. 5. 2. Solve for the variables. 5
  6. 6. 3. Solve for the variables. 6
  7. 7. 4. Solve for the variables. 7
