Geometry Chapter 8
We are familiar with the Pythagorean Theorem:
For each triangle, use the Pythagorean theorem to find the length of the hypotenuse. Leave the answer in simplest radical form
solve for the missing sides – leave you answer in radical form.

Warm Up
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
This trigonometric ratio is called the tangent ratio.
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
