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!
