🔺 How to Use the Triangle Calculator
Our Triangle Calculator helps you find the sides, angles, area, and perimeter of any triangle — whether you know three sides (SSS), two sides and an angle (SAS), or one side and two angles (AAS).
Simply select the correct tab for your known values, enter the measurements, and click “Calculate.” The calculator will instantly show the missing sides and angles, the triangle’s area and perimeter, and a visual diagram of the triangle scaled to fit.
Example Uses
- SSS (Three Sides Known): If the sides are 5, 7, and 9, the calculator finds all angles, area, perimeter, and displays a diagram.
- SAS (Two Sides + Included Angle): For sides 6 and 8 with a 60° included angle, it calculates the missing side, angles, area, perimeter, and diagram.
- AAS (One Side + Two Angles): Given side 7 and angles 50° and 60°, it finds the remaining side and angle, area, perimeter, and shows the triangle visually.
This tool is perfect for students, engineers, architects, and teachers who need quick, accurate triangle calculations with clear step-by-step results.
