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.
The Acute Triangle has three acute angles (an acute angle measures less than 90Â°) Obtuse Triangle The Obtuse Triangle has an obtuse angle (an obtuse angle has more than 90Â°). In the picture on the left, the shaded angle is the obtuse angle that distinguishes this triangle Since the total degrees in any triangle is 180Â°, an obtuse triangle can only have one angle that measures more than 90Â°.
