Supplementary Angles (Quick Exploration)
[color=#000000]In the applet below, the [/color][b][color=#ff00ff]pink angle[/color][/b][color=#000000] and the [/color][b][color=#1e84cc]blue angle[/color][/b][color=#000000] are said to be [/color][b][color=#000000]supplementary angles[/color][/b][color=#000000]. [br][br]Interact with this applet for a minute or two, and answer the questions that appear below it.[/color]
1.
In your own words, describe what it means for 2 angles to be supplementary angles.
2.
[color=#000000]In the applet above, the [/color][b][color=#1e84cc]blue angle[/color][/b][color=#000000] is said to be a [/color][i][color=#000000][b]supplement [/b][/color][/i][color=#000000]of the [/color][color=#ff00ff][b]pink angle[/b][/color][color=#000000], and vice versa.[br][/color][color=#000000]Given this information, determine the [/color][i][color=#000000]supplement[/color] [/i][color=#000000]of a 130 degree angle. [/color]
