Here's how to use this file to explore[color=#fff2cc] [b]Circular Measurement (in Radians)[/b] [/color]and understand the [color=#38761d][b]Central Angle Theorem[/b].[br][b]Before You Begin[/b][/color][br]Take a moment to think about: [list][*]What is circular measurement in radians? [/*][*]What is the central angle of a circle? [/*][*]How can this file help you understand these concepts better?[/*][/list][b][color=#ff0000]Steps to Use the File:[/color][/b][list=1][*] [b]Click the First [color=#ffd966]Play[/color] Button[/b] [/*][list][*]Watch what happens: the [color=#ff0000]radius becomes equal to the arc[/color] on the circle's circumference. [/*][*]Now, [b]slide the point[color=#ff0000] "Rakesh Ghimire" [/color][/b]to explore it again and understand more clearly.[/*][*]Think: [i]How can we prove that 1 radian is a constant angle?[/i][/*][/list][*][b]Click the "Solution" Button[/b] [/*][list][*]You will see three more buttons: [color=#00ff00][b]Next[/b], [/color][color=#00ffff][b]Back[/b], [/color]and [color=#f4cccc][b]Reset[/b].[/color][/*][*]Click [b][color=#00ff00]Next[/color][/b] to go through the proof step by step.
