How to Use the Advanced Triangle Calculator

Welcome to the ultimate Triangle Calculator. This free online tool helps students, engineers, and architects solve complex geometry problems instantly. Whether you need to find the area, perimeter, or unknown angles of a triangle, our calculator supports all standard methods including SSS, SAS, ASA, and AAS.

Calculation Methods Explained

• SSS (Side-Side-Side): Use this when you know the length of all three sides. The tool uses Heron's Formula and the Law of Cosines.
• SAS (Side-Angle-Side): Use this when you know two sides and the angle between them.
• ASA (Angle-Side-Angle): Ideal for when you have two angles and the included side length.
• AAS (Angle-Angle-Side): Solves the triangle when two angles and a non-included side are known.

Why Use This Tool?

Unlike basic calculators, this tool provides a visual representation of your triangle, ensuring you understand the geometry. Plus, with our built-in history feature and PDF/CSV export options, you can save your work for homework or professional projects.

Key Features

• Instant Area & Perimeter calculation.
• Accurate Angle determination in degrees.
• Identification of triangle type (Equilateral, Isosceles, Scalene, Right, Obtuse).
• Mobile-friendly design for calculations on the go.
