Pythagorean Theorem Calculator
Hypotenuse Length:
Pythagorean Theorem Calculator Tool
Looking for a quick way to find the length of a triangle’s missing side? The Pythagorean Theorem Calculator is your go-to tool. Whether you’re a student, engineer, or someone who simply loves math, this tool simplifies problem-solving for right triangles. By entering just two known side lengths, the Pythagorean Theorem Calculator on hcalculator can instantly calculate the third.
What is the Pythagorean Theorem?
The Pythagorean theorem is a mathematical rule that applies to right triangles. It states:
a² + b² = c²
Here:
- a and b represent the legs (shorter sides)
- c is the hypotenuse (the longest side, opposite the right angle)
This formula is only valid when one angle in the triangle is 90 degrees.
Pythagorean Theorem for Right Triangles
Undeniably, the right triangle calculator uses this core formula to find any missing side. Not only is it simple, but it’s also efficient. This makes it suitable for geometry, design, and construction projects. When precision matters, this tool saves time.
Pythagorean Theorem Formula
The formula is elegantly simple:
a² + b² = c²
It means the sum of the squares of the two sides equals the square of the hypotenuse. With any two known values, you can easily compute the third.
How to Use the Pythagorean Theorem Calculator?
Using this tool on hcalculator is straightforward:
Solve for the Length of the Hypotenuse c
If you know an and b, the calculator uses: c = √ (a² + b²)
Solve for the Length of Side a
If you know b and c, then: a = √ (c² – b²)
Solve for the Length of Side b
If you know a and c, then: b = √ (c² – a²)
Solve for Area A of the Right Triangle
You can also find the area: Area = (a × b) ÷ 2
Input Values and How the Equation Works
Simply input any two sides, and the calculator solves the equation step-by-step. This makes it a helpful learning tool in addition to being a quick reference.
What is the Hypotenuse Given Legs 7 and 9?
For example, if a = 7 and b = 9: c = √(7² + 9²) = √(49 + 81) = √130 ≈ 11.40
What is the Hypotenuse Formula?
Again, the standard formula is: c = √(a² + b²)
This side is always the longest and lies opposite the right angle.
What are Pythagorean Triples?
Pythagorean triples are sets of whole numbers that fit perfectly in the theorem:
- (3, 4, 5)
- (5, 12, 13)
- (7, 24, 25)
These are useful when working with clean, integer-based problems.
Other Considerations When Dealing with Triangles
Perimeter of a Right Triangle
Perimeter = a + b + c
Area of a Right Triangle
Area = (base × height) ÷ 2
Diagram and Visual Aid
Visualizing a diagram of a right triangle helps you understand which sides are legs and which is the hypotenuse.
