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 do I need to use the Right Triangle Calculator?
You need at least two pieces of information: either two sides, one side and one angle, or the area and one side. The calculator will automatically determine which method to use based on your input.
How does the Right Triangle Calculator use the Pythagorean theorem?
When you provide two sides of the right triangle, the calculator uses the Pythagorean theorem (a² + b² = c²) to find the third side. It shows each step of the calculation, including squaring the sides, adding them, and taking the square root.
Can the calculator find angles in a right triangle?
Yes! The calculator can find all angles in a right triangle. It uses trigonometric functions (sine, cosine, tangent) and inverse trigonometric functions to calculate angles from side lengths, or side lengths from angles.
Does the Right Triangle Calculator show the area and perimeter?
Yes, once all sides are calculated, the calculator automatically computes the area (½ × base × height) and perimeter (sum of all three sides). It shows the formulas and calculation steps for both.
How accurate are the calculations?
Our calculator provides high-precision calculations with decimal accuracy. For angles, it provides results in both degrees and can show radians if needed.
Is the Right Triangle Calculator free to use?
Yes! Our Right Triangle Calculator is completely free to use. Solve unlimited right triangle problems without any cost or registration required.
