Right Triangle Calculator
Calculate sides, angles, and area of right triangles
Our Right Triangle Calculator is a comprehensive tool designed to help you solve problems involving right triangles. Whether you know two sides and need to find the third, or know one side and an angle, our calculator can find all missing measurements. It uses the Pythagorean theorem for side calculations and trigonometric functions (sine, cosine, tangent) for angle and side relationships. The calculator provides step-by-step solutions showing all formulas used, making it perfect for students learning geometry and trigonometry, as well as professionals working with construction, engineering, or design projects.

Frequently Asked Questions About Right Triangle Calculator
Common questions about our right triangle calculator
What information is needed?
You need at least two pieces of information: either two sides, one side and one angle, or the area and one side. The platform will automatically determine which method to use based on your input.
How is the Pythagorean theorem applied?
When you provide two sides of the triangle, the platform uses a² + b² = c² to find the third side. It shows each step of the calculation, including squaring the sides, adding them, and taking the result.
Can angles be calculated?
Yes! The platform can find all angles in the triangle. It uses trigonometric functions (sine, cosine, tangent) and inverse versions to calculate angles from side lengths, or side lengths from angles.
Are area and perimeter shown?
Yes, once all sides are calculated, the platform automatically computes the area (½ × base × height) and perimeter (sum of all three sides). It shows the formulas and calculation steps.
How precise are the calculations?
The platform provides high-precision calculations with decimal accuracy. For angles, it provides results in both degrees and can show radians if needed.
Is there a cost?
No! The platform is completely free to use. Solve unlimited problems without any cost or registration required.
