Copy of Right Triangle Trigonometry: Intro
This applet accompanies the Right Triangle Trigonometry: Intro activity packet you received at the beginning of class today. Use this applet to help you complete the guiding questions in this activity.
Key Question:
Hopefully, you noticed that when you keep the blue angle fixed and move only the white vertices, the value of each ratio never changes (even though the side lengths do)! Why does this occur? Explain!
This happens because the value of a right triangle never changes, otherwise, it would not be a right triangle. Also, the blue angle never changes even though it changes size. That is why the values never change.
