[color=#000000][b]Questions:[/b][/color][br][br][color=#000000]1) In your own words, describe what it means for 2 angles to be supplementary angles. [br][br][/color][color=#000000]2) 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. [br][br][/color][color=#000000]3) What is the supplement of a 1-degree angle? [br][br][/color][color=#000000]4) What angle measure has a supplement whose measure is equal to itself? [/color]
