Content Standards and Benchmarks:

II,3,1: Select and use appropriate tools; make accurate measurements using both metric and common units, and measure angles in degrees and radians.

          II,3,5: Use proportional reasoning and indirect measurements including applications of trigonometric ratios, to measure inaccessible distances and to determine derived measures such as density.

Objective:

After a class discussion the previous few days regarding the application of Trigonometric Ratios and the Law of Sines students will be able to complete the worksheet given to them.

Introduction:

Warm-up:

          Review how to use Trigonometric Ratios and the Law of Sines as a group before doing the worksheet as a group.

Guided Practice:

Students will work through the next few problems on the worksheet they are given.  We will then check them together as a group.

Independent practice:

Students will be assigned Ex Set 2 #1-6, and Pg 40, M #2 due tomorrow.

Closure:

Ø     As a class we will review when we can use the Law of Sines

-         In what type of triangle?

-         What types of info do you need to know?
