Features
Read full description

The best app to calculate all quantities of an arbitrary triangle. You must enter some quantities like two angles and one length. The algorithm searches the formulas of the missing quantities, shows them and calculates the results. The length of the decimal place can be changed. The algorithm shows when rounding or wrong values lead to an opposition. Decimals and fractions are supported. The solution is shown step by step. All calculations are stored in the history. The final solution can be shared. [ Contents ] - all important quantities for the arbitrary triangle - formulas for all important quantities of an arbitrary triangle - infographic to illustrate the topic - search bar to find the desired quantity - history function to save the input - detailed solution - positive numbers, decimals and fractions are supported - no ads! [ Usage ] - there are fields for entering values using a special keyboard - press the check mark button at the bottom right to start the calculation - if values are missing, all fields will be marked orange - if the values are wrong (e.g. negative lengths), the affected field will be highlighted red - if a value is no number, it is highlighted in red - the entries in the history can be deleted or sorted - if you select an entry in the history, it will be automatically loaded for the calculation - the whole history can be deleted by pressing a button - solutions can be shared [ Math conditions ] - each value must be greater than zero - each angle must be less than 180° - the sum of two sides must always be greater than the length of the third side
