The théorème de Pythagore explication simple and its reciprocal theorem are fundamental mathematical concepts for solving right triangle problems. The theorem enables calculation of unknown side lengths in right triangles, while its reciprocal helps determine if a triangle is right-angled.

• The Pythagorean theorem states that in a right triangle, the square of the hypotenuse equals the sum of squares of the other two sides
• Comment utiliser le théorème réciproque de Pythagore: If the square of the longest side equals the sum of squares of other sides, the triangle is right-angled
• Multiple exemples de calcul triangle rectangle avec Pythagore demonstrate practical applications
• Clear step-by-step calculations show how to find missing lengths and verify right angles
• The theorem and its reciprocal are essential tools for geometry problems, including those in standardized tests
