## Isosceles Triangle PRO Description
The best app to calculate all quantities of an isosceles triangle. You must enter some quantities like an angle and a length. The algorithm searches the formulas of the missing quantities, shows them and calculates the results.

The calculation of an isosceles triangle depends on one certain characteristic. Either it is obtuse angled or acute angled. Both is handled in this app. You just have to touch the button to switch the appearance of your isosceles triangle.

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.

[ Content ]
