4.1. Triangle Sums http://www.ck12.org
Know What? RevisitedThe Bermuda Triangle is an acute scalene triangle. The angle measures are in the picture
below. Your measured angles should be within a degree or two of these measures. The angles should add up to 180◦.
However, because your measures are estimates using a protractor, they might not exactly add up.
The angle measures in the picture are the measures from a map (which is flat). Because the earth is curved, in real
life the measures will be slightly different.
