Geometry Video on Putting Calculators in Degree Mode
For solving triangles you will most likely have the angles measured in degrees. In a trigonometry class students use both degrees and radians to measure angles. As a result, calculators can be put in either degrees or radians. In geometry we mostly use degrees. You do not need to worry about what radians are at this point, but you do need to worry about the settings on your calculator to make sure your calculator is in degrees. This video addresses that issue.
