Opener: Find your Colored Rectangle Group. You have 10 minutes to put your best possible Theoretical Values into the chart on the board.
SLT Triangles 1: I can use similarity to define trigonometric ratios as properties of the angles in a triangle.
 You just used everyone’s empirical data from Part 1 of this project to determine your theoretical value for each of the ratios: a/e, b/e, and a/b.
How do you know if your theoretical values are accurate?
 What are the properties of similar triangles?
 Let’s measure the angles in each of our triangles.
 Let’s use these angles to check out answer.
In conclusion:

The trigonometric ratios are SINE, COSINE, and TANGENT

These ratios are properties of the angles in similar triangles.

So, are rectangles and squares similar?
