How to Use the Pythagorean Theorem. Step By Step Examples …
Use the Pythagorean theorem to determine the length of X. Identify the legs and the hypotenuse of the right triangle. The legs have length 6 and 8. X X is the hypotenuse because it is opposite the right angle. Substitute values into the formula (remember 'C' is the hypotenuse). A2 + B2 = C2 62 + 82 = X2 A 2 + B 2 = C 2 6 2 + 8 2 = X 2.

Here you will learn about the Pythagorean Theorem, including how to find side measurements of a right triangle and using Pythagoras’ theorem to check and see if a triangle has a right angle or not. Students will first learn about Pythagorean Theorem as part of geometry in 8 th grade and continue to use it in high school.
How to Prove the Pythagorean Theorem: 10 Steps (with Pictures) - wikiHow
2024年10月2日 · The Pythagorean Theorem is a generalization of the Cosine Law, which states that in any triangle: c² = a² + b² - 2(a)(b)(cos(C)), where C is the angle opposite side c. In a right triangle, where a and b are the legs, and c is the hypotenuse, we have (because the right angle is opposite the hypotenuse): c² = a² + b² - 2(a)(b)(cos(90)).
