Сразу же (не давая увидеть функционал) просят бабок. Удаляю. 😂
Проще взять калькулятор и посчитать самому, чем открывать это чудо, смотреть рекламу да ещё и за бабки.

Response from developer

Привет, gfugdhjcsjjcdf, ты прав, система работала некорректно. Приношу извинения. Она полностью переработана. Сторонняя реклама также убрана (из-за неё и возникали проблемы). Если что-то ещё не работает, пожалуйста, дай мне знать. Ваши «Вологодские чайки».

why not include the angles?

I wanted to know the angles of a triangle for a woodworking project, which is why I downloaded this app. Why on earth wouldn’t the designer include that in the answers? Irritating. $2 misspent.

FAQ

What does the Solving Pythagoras app do?

This app calculates the sides of a right-angled triangle using the Pythagorean theorem. You can input the values of two sides, and the app will automatically calculate the third side. It also stores all your calculations in a history for easy access and sharing.

How do I calculate a triangle side?

To calculate a triangle side, simply enter the values for two of the edges (a, b, or c) into the designated fields. The app will then use the Pythagorean theorem to compute the value of the missing third edge. The input fields are highlighted to guide you if not enough values are entered.

Is there a cost to use Solving Pythagoras?

The app is free to download and use, with an option to remove ads through an in-app purchase. This allows you to enjoy an ad-free experience for your calculations.

What devices is Solving Pythagoras compatible with?

While specific OS versions are not detailed, the app is designed for mobile devices. It features a modified keyboard for input and allows navigation between input, solution, and history views via swiping and button touches.

Can I save and share my calculations?

Yes, all calculations performed in the app are automatically saved in a history function. You can select entries from the history to load them for further calculation or editing, and the final solutions can be shared.
