Thanks to http://www.geogebra.org/user/profile/id/500439 for this v nice applet
Questions: 1) In your own words, describe what it means for 2 angles to be supplementary angles. 2) In the applet above, the blue angle is said to be a supplement of the pink angle, and vice versa. Given this information, determine the supplement of a 130 degree angle. 3) What is the supplement of a 1-degree angle? 4) What angle measure has a supplement whose measure is equal to itself?
