Quadrantal angles (0, 90, 180, and 270 degrees), and the values of the sine, cosine, and tangent of each of these angles. From the trig lessons in the Algebra 2 course by Derek Owens.
An acute angle is an angle with a measure between 0 and 90 degrees. An obtuse angle is an angle with a measure between 90 and 180 degrees. Two angles are complementary if the sum of their measures is equal to 90 degrees. Example: angles a and b with measures a = 19 and b = 71 are complementary since a + b = 90.
