## Description

Triangle Math is a versatile Chrome extension designed to solve any type of triangle efficiently by inputting at least three parameters—either sides or angles. It automatically displays the solved triangle along with all related calculated values, making trigonometry accessible and straightforward.

This extension not only provides results but also offers transparency by showing the mathematical methods behind each calculation, including solved literal equations. It implements key mathematical laws such as the Law of Sines, Law of Cosines, angle sums, Heron's formula, and surface area formulas. For right triangles, it supports the Pythagorean theorem and trigonometric ratios like sine, cosine, and tangent.

Triangle Math supports both degrees and radians, allowing the input of special angles in radian format (e.g., π/2, π/3). It's ideal for students, educators, professionals in architecture, construction, and anyone needing quick, accurate triangle solutions. This app is a must-have for enhancing understanding and application of trigonometry.

## Review summary

Users appreciate the app for its simplicity, ease of use, and clear interface, ideal for quick and precise triangle calculations without extra tutorials. It is especially helpful for applications like carpentry. However, multiple users reported a minor bug in the law of cosines formula where the sign is incorrect, affecting formula accuracy. Overall, it is considered one of the best and user-friendly trigonometry calculators with minimal downsides.

### Pros

- Very easy to use and simple interface.
- Provides precise calculations of all sides and angles of triangles.
- Includes helpful formulas and calculates results without unnecessary explanations.
- No ads and great UI design.
- Perfect for specific use cases like carpentry where quick answers are needed.

### Cons

- Minor bug in the law of cosines formula displaying a plus symbol instead of minus.
- Occasional errors in formula representation noted.
- One review simply states 'Bekar' (useless), indicating some dissatisfaction but not elaborated.
