Solve Right Triangles with the Pythagoras Theorem

The relationship between the sides of a right triangle is one of the most famous results in mathematics. The Pythagoras Theorem Solver on ToolDeft lets you find the missing side of any right triangle by entering the two known sides. Whether you need the hypotenuse or one of the legs, this tool delivers the answer instantly with the working shown.

What Is the Pythagoras Theorem?

The Pythagoras theorem states that in a right-angled triangle, the square of the hypotenuse equals the sum of the squares of the other two sides. Written as a formula: a squared plus b squared equals c squared, where c is the hypotenuse. This theorem has been known for over 2,500 years and remains one of the most frequently used formulas in mathematics, engineering, architecture, and physics.

How the Solver Works

Enter the lengths of two sides. If you provide both legs a and b, the tool calculates the hypotenuse c. If you provide the hypotenuse and one leg, it calculates the missing leg. The tool shows the formula, the substitution step, and the final answer rounded to the precision you choose. It also verifies the result to confirm the calculation is correct.

Who Uses This Tool?

Students solving geometry and trigonometry problems. Teachers creating practice worksheets and answer keys. Carpenters and builders checking diagonal measurements to ensure corners are square. Surveyors calculating distances. DIY enthusiasts cutting materials at precise angles. Game developers computing distances between objects in 2D space. The Pythagoras theorem is everywhere, and so is the need to solve it quickly.

Real-World Applications

A carpenter wants to verify that a door frame is perfectly square. Measure 3 feet along one edge, 4 feet along the other, and the diagonal should be exactly 5 feet. A hiker wants to know the straight-line distance between two points on a map when they know the horizontal and vertical distances. An architect calculates the length of a roof rafter from the span and the rise. In each case, the Pythagoras Theorem Solver provides the answer instantly.

Fast, Free, and Private

The Pythagoras Theorem Solver runs in your browser with zero server interaction. Your measurements stay on your device. Results are instant and include clear step-by-step working. Bookmark it for geometry homework, construction projects, or any situation where a right triangle needs solving.
