About Triangle Calculator
This triangle calculator helps you solve various triangle properties including:
- Area (using base/height or Heron's formula)
- Perimeter and semi-perimeter
- All three angles (sum must equal 180°)
- Missing sides using the Law of Sines or Cosines
- Right triangle properties (Pythagorean theorem)
The calculator supports multiple calculation methods:
- SSS (Side-Side-Side): When you know all three sides
- SAS (Side-Angle-Side): When you know two sides and the included angle
- ASA (Angle-Side-Angle): When you know two angles and the included side
- SSA (Side-Side-Angle): When you know two sides and a non-included angle
Triangle Calculator Answers
What does the triangle calculator do?
It helps you calculate unknown sides, angles, area, perimeter, and other properties of different types of triangles using formulas like Pythagoras, Law of Sines, and Law of Cosines.
What types of triangles can it handle?
The calculator works with right, acute, obtuse, equilateral, isosceles, and scalene triangles.
What information do I need to provide?
You can enter a combination of sides and angles. The calculator will use these to find the missing measurements.
Is this useful for students and engineers?
Definitely. It’s great for geometry homework, construction projects, and any field requiring accurate triangle calculations.
