Triangle Solver
Solve sides using the Pythagorean Theorem.
Enter any two sides to calculate the third and the total area.
Understanding the Right Triangle Calculator
Mathematically solve any right-angled triangle using the Pythagorean Theorem. Calculate side lengths and total surface area with real-time scaling and visual feedback.
How to use the Right Triangle Calculator
- 1Enter the lengths of at least two known sides of your right triangle.
- 2Input 'Leg a' and 'Leg b' to find the hypotenuse.
- 3Input the 'Hypotenuse c' and one of the legs to find the missing leg.
- 4The calculator will automatically display the side lengths and total area.
Common Use Cases
The Maths Behind the Calculation
a² + b² = c² | Area = ½(a × b)The tool utilizes algebra to isolate the missing variable and also calculates the area by treating the two legs as base and height (90-degree intersection).
Frequently Asked Questions
What is the Pythagorean Theorem?
It is a mathematical formula (a² + b² = c²) that relates the lengths of the three sides of a right triangle.
Why do I need two sides?
A single side length is not enough to define the shape. Standard geometry requires at least two measurements to solve for the third in a right triangle.
Does this work for 45-45-90 triangles?
Yes, it works for any triangle that has one 90-degree angle, regardless of the other two angles.
