As discussed in an earlier module, the 30-60-90 triangle is a special triangle with side length ratios of 1 - V3 - 2. Here, we will focus on this triangle when the reference angle is 30. Note that this triangle can be rotated around the Cartesian plane, which will be illustrated in this example. Use the graphics below to label the side lengths for the corresponding given angles. Watch your signs. Diagram Q2n Angle 0 = 30 = 71/6 = 150 = 57/6 8 = 210 = 77/6 0 = 330 = 117/6 OPP Side Length ADJ Side Length HYP Side Length Submit
