Included angle math
WebTwo angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees. One way to avoid mixing up these definitions is to note that s comes after c in the alphabet, and 180 is greater than 90. 12 comments ( 68 votes) Upvote Downvote Flag more Show more...
