Tired of dealing with Pythagoras' theorem, law of sines, law of cosines and other trigonometric formulas? TriangleCalc lets you easily calculate any oblique, right-angled or isosceles triangle. Just select the sides and angles given, type in the values and if the number of inputs is sufficient to solve the triangle, the application does the rest for you. It's as simple as that. In addition, TriangleCalc lets you lock up to two values, so that they will not be erased if you start a new calculation. This feature is especially useful if you want to calculate a number of variants of your triangle.

I was kinda reluctant when I was looking at this app but I decided to buy it and I'm glad I did! This app has helped me so much in my trigonometry class! Great buy for a dollar!
