Triangle Calculator

The application calculates the lengths, angles, area and perimeter of a right-angle triangle when only 2 values are known. A proportionally correct triangle is drawn according to calculations. The proportions of the triangle are consciously incorrect if any angle is too small. If the proportions are not OK a message alerts you to this. The shown triangle can be rotated and flipped. The number of decimals for lengths, angles, area and perimeter (according to lengths) can be specified. Note that the results may be rounded if they are to be used! It is possible to reuse and edit the most recently entered values after clearing. It is possible to change the color theme on backgrounds. Note that the results are given with a maximum of ~15 significant digits (all calculations are made in 64-bit double precision).
