Student Learning Target:
I can use similarity to define trigonometric ratios as properties of the angles in a right triangle.
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.
The trigonometric ratios are SINE, COSINE, and TANGENT
These ratios are properties of the angles in similar triangles.
So, are rectangles and squares similar?
But wait, what are the trig ratios (and how can I remember them)?
Let’s build some reminders for ourselves!
