1. Geometry Chapter 8

2.  We are familiar with the Pythagorean Theorem:

9.  For each triangle, use the Pythagorean theorem to find the length of the hypotenuse. Leave the answer in simplest radical form. 2 2 5 5 4 4

15.  solve for the missing sides – leave you answer in radical form.

16.  Homework: 420 (1-25) odd  428 (1-15) odd

17.  Warm Up

18.  For each pair of complementary angles ∠A and ∠B, there is a family of similar right triangles.  In each family the ratio:  is constant no matter the size of ∆ABC

19.  This trigonometric ratio is called the tangent ratio.

25.  One way to remember which ratio corresponds to each trig function is to remember the word: SOH-CAH-TOA  SOH: sine opposite over hypotenuse  CAH: cosine adjacent over hypotenuse  TOA: tangent opposite over adjacent
