Question 832450
<pre>
Hi, there--

Two angles are COMPLEMENTARY if the sum of their measures is 90 degrees.
For example, a 30-degree angle and a 60-degree angle are complementary because 30+60=90.

Two angles are SUPPLEMENTARY if the sum of their measures is 180 degrees.
For example, a 30-degree angle and a 150-degree angle are supplementary because 30+180=90.

Hope this helps!
