a 2 + b 2 = c 2. This is known as the Pythagorean equation, named after the ancient Greek thinker Pythagoras. This relationship is useful because if two sides of a right triangle are known, the Pythagorean theorem can be used to determine the length of the third side. Referencing the above diagram, if. a = 3 and b = 4.
Construct a second triangle with sides of length a and b containing a right angle. By the Pythagorean theorem, it follows that the hypotenuse of this triangle has length c = √ a 2 + b 2, the same as the hypotenuse of the first triangle. Since both triangles' sides are the same lengths a, b and c, the triangles are congruent and
The Pythagorean theorem states that if a triangle has one right angle, then the square of the longest side, called the hypotenuse, is equal to the sum of the squares of the lengths of the two shorter sides, called the legs. So if a a and b b are the lengths of the legs, and c c is the length of the hypotenuse, then a^2+b^2=c^2 a2 + b2 = c2.
Jul 26, 2024 · To arrive at this answer, we apply the Pythagorean theorem: Recall the formula a² + b² = c², where a, and b are the legs and c is the hypotenuse. In our case, a = b, so the formula reads 2a² = c². Solving for a, we get a = c/√2. Plugging in c = 10, we get the final answer: a = 10/√2 ≈ 7.07. a2 + b2 = c2.

The Pythagorean Theorem states that the sum of the squared sides of a right triangle equals the length of the hypotenuse squared. You might recognize this theorem in the form of the Pythagorean equation: If you know the length of any 2 sides of a right triangle you can use the Pythagorean equation formula to find the length of the third side.
This calculator solves the Pythagorean Theorem equation for sides a or b, or the hypotenuse c. The hypotenuse is the side of the triangle opposite the right angle. For right triangles only, enter any two values to find the third. See the solution with steps using the Pythagorean Theorem formula. This calculator also finds the area A of the right tr...
Using the Pythagorean Theorem formula for right triangles you can find the length of the third side if you know the length of any two other sides. Read below to see solution formulas derived from the Pythagorean Theorem formula:
A Pythagorean triple is a set of 3 positive integers for sides a and b and hypotenuse c that satisfy the Pythagorean Theorem formula a2 + b2 = c2 The smallest known Pythagorean triple is 3, 4, and 5. Showing the work:

Jul 28, 2024 · Besides the two sides, you need to know one of the inner angles of the triangle. Let's say it's the angle γ = 30° between the sides 5 and 6. Then: Recall the law of cosines formula c² = a² + b² - 2ab × cos (γ) Plug in the values a = 5, b = 6, γ = 30°. We obtain c² = 25 + 36 - 2 × 5 × 6 × cos (30) ≈ 9. Therefore, c ≈ 3.
