This calculator completes the analysis of any triangle be it a obtuse triangle, acute triangle, right triangle, or irregular triangle. Please input only three values and leave the values to be calculated blank. If all the inputs are angles the calculator will calculate the proportionate length of the sides which can then be used to scale up depending on actual size requirements. In this case please input only two angles and the other four unknowns will be calculated. In the case where two solutions to the same inputs are possible this calculator will give the two solutions.
