## Description

The Triangle Calculator is a powerful trigonometry tool designed to simplify solving right-angled triangles when two values are known (one must be a length). It calculates lengths, angles, area, and perimeter with ease. The extension features a proportionally correct triangle drawing that you can rotate and mirror for better visualization. Users can specify decimal precision for measurements and color themes for the background to enhance usability. Additionally, the tool allows reusing and editing previous inputs even after clearing them, making repetitive calculations convenient and efficient.

## Review summary

Users appreciate the Triangle Calculator app for its simplicity, clear and attractive interface, and practical usefulness at work and home. It is also praised for being ad-free with a clear privacy policy, precise calculations, and a visual feature that allows rotating the triangle for better understanding. However, several users find it inconvenient that after obtaining results, they cannot edit individual inputs without re-entering all values. Additionally, the app only supports calculations for right triangles, which limits its scope.

### Pros

- Simple and easy to use with a clear and visually attractive user interface
- Very useful for work and home purposes involving right triangles and trigonometry
- Free of ads and has a readable privacy policy
- Allows visualizing triangles by changing shape and rotation
- Good precision in calculations

### Cons

- Cannot change individual input values after entering them; has to re-enter all values
- Only supports right triangle calculations
