Supplementary Angles Exploration
In the applet below, the pink angle and the blue angle are said to be supplementary angles.
Interact with this applet for a minute or two, and answer the questions that appear below it.
Directions
Copy and paste the following questions into a google doc. Then answer the questions within the same google doc.
1) Based on your observations, what can be said about supplementary angles? 2) Suppose the measure of blue angle above is 130 degrees. Hmm... what do you think the measure of the pink angle would be and why do you think that?
