To convert degrees to radians multiply the degrees by pi over 180 degrees.
To convert radians to degrees multiply by 180 degrees over pi.
We also learned about positive and negative coterminal angles.
To find a positive coterminal angle you add 360 degrees.
To fine a negative coterminal angle you subtract 360 degrees.
Today we learned about supplementary and complementary angles and how to find the area of a Sector.
Supplementary angles are two angles with the sum 0f 180 degrees.
Complementary angles are two anglies with the sum of 90 degrees.
