Right triangle calculator for calculating missing sides, angles, area, and properties using Pythagorean theorem and trigonometry. Enter at least 2 values (legs, hypotenuse, or angles) to find unknowns in right-angled triangles. Visualize with dynamic drawings showing results on the triangle image, plus multiple charts for sides, angles, scaling, properties, and trigonometric functions. Detailed formulas, examples, explanations on how to find the hypotenuse, legs, or angles in right triangles.
After calculation, see a custom drawing of your right triangle with embedded results (sides, angles, area), plus charts visualizing every aspect: bar for sides, pie for angles, line for scaling, radar for properties, doughnut for trig functions, bar for medians, and polar for trig ratios.
This right triangle calculator uses Pythagorean theorem (a² + b² = c²) and trigonometric functions (sin, cos, tan) to compute missing sides and angles in right-angled triangles. Ideal for finding the hypotenuse from two legs, or angles from sides. Enter values, and get instant results with visualizations.
Example: For legs A=3, B=4 – hypotenuse C=5, angles α=36.87°, β=53.13°, area=6. Charts show side distributions, angle pie, and more for better understanding.
Key formulas include:
Our tool handles cases with only one side and an angle, using trig to solve. For example, if only hypotenuse and one angle known, find legs with sin/cos. Visualizations include charts for trig values (doughnut) and scaling (line) to see how changes affect the triangle.
Right triangles are fundamental in geometry, engineering, physics, and architecture. Use this calculator to solve problems like finding the height of a ladder (hypotenuse) or roof pitch (angles). All calculations are accurate, with dynamic drawings showing labels directly on the triangle for educational purposes.

How to find missing side with one side and angle? Use trig: opposite = hypotenuse * sin(angle). Our calculator automates it with charts.
Supports radians? Yes, select unit and input pi/6 for 30°.
Why multiple charts? For professional analysis – visualize sides, angles, properties, trig in one place for user experience.
Is it accurate for large values? Yes, handles floating-point precision for engineering applications.
