TriangleTriangle is a neat program that lets you find all the sides and angles of a triangle, as well as the area. After you choose degrees or radians, press the number of what you want to do (law of cosines, law of sines, area by side angle side, area by side side side, or law of angle side side). For the law of cosines, if you want to find the length of a side, put in zero for c, and if you want the angle measure, put in zero for d. In the law of sines, you are solving for d. When it says something like "Area X=6.4436," X is the variable the answer is stored in, if you want to use it in the run mode or in the program again. |
