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.
Some triangles will have one angle that is exactly 90 degrees. Those are right triangles because one angle is 90 degrees. (The other two angles must be acute because they must add up to 90 degrees.) Some triangles will have one angle that is more than 90 degrees. Those are obtuse triangles because one angle is obtuse. (The other two angles are acute because the sum of the other two triangles is less than 90 degrees). Some triangles will have all three angles less than 90 degrees. Those are the acute triangles. Go ahead, start with a right triangle.
