Solving triangles is a fundamental skill in geometry and trigonometry, with applications in construction, navigation, engineering, and design. This triangle calculator can solve any triangle given sufficient information: three sides (SSS), two sides and an included angle (SAS), two angles and an included side (ASA), or simply a base and height for area calculations. It computes all missing sides, all three angles, the total area using Heron's formula where appropriate, and the perimeter, all in one calculation. Whether you're a student working through trigonometry problems or a professional needing quick measurements for a real-world project, this tool handles the math instantly.
