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 ] - all important quantities for the isosceles triangle - formulas for all important quantities of an isosceles 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 - changeable decimal place - changeable appearance of your triangle (obtuse angled - acute angled) - no ads! [ Usage ] - there are several fields for entering the values ​​using a special keyboard - if values are missing, all fields are highlighted in orange - if values are conflicting or wrong (e.g. negative lengths), one affected field is highlighted in red - every value must be positive - if a value is no number, it is highlighted in red - the entries in the history can be deleted or sorted manually - if you select an entry in the history, it will be loaded automatically for the calculation - the entire history can be deleted by pressing a button - solutions can be shared [ Acute angled ] - gamma must be less than 90° - alpha must be greater than 45° and less than 90° [ Obtuse angled ] - gamma must be greater than or equal 90° and less than 180° - alpha must be less than or equal 45°
