Right Triangle Trigonometry: Intro
[color=#000000]This applet accompanies the [/color][i][color=#0000ff]Right Triangle Trigonometry: Intro[/color][/i][color=#000000] activity packet you received at the beginning of class today. Use this applet to help you complete the guiding questions in this activity. [/color]
[color=#980000][b]Key Question: [/b][/color] [br][br][color=#000000]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)! [/color][color=#ff00ff][i]Why does this occur? [/i] Explain! [/color]
