WebMar 17, 2024 · When the hypotenuse of a 30 60 90 triangle has length c, you can find the legs as follows: Divide the length of the hypotenuse by 2. Multiply the result of Step 1 by √3, i.e., by about 1.73. The number you've got in Step 1 is the shorter leg of your triangle. The number you've got in Step 2 is the longer leg. WebLubin suggested using the Cosine Law for the first calculation and the Sine Law for the second. This is faster than Cosine Law done twice. The suggestion is to use the Cosine Law to determine the angle opposite a largest side. Then we will know that the other angles are acute, so Sine Law goes smoothly. This works for all triangle types ... WebMay 2, 2024 · Use a ruler and a protractor to measure the sides \(a, b, c\) and the angles \(A, B, C\) of the triangle.
