The final step is to determine the principal square root of both sides of the equation.
The triangle XYZ is a right triangle.
The sides "a" and "b" are the height and the base of the triangle.
The side "c" is the hypotenuse of the triangle.
The Pythagoreantheorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
The side lengths must satisfy the Pythagorean theorem, a² + b² = c².
It is also an isosceles triangle, so the equation becomes a² + a² = c².
By combining like terms, we get 2a² = c².
The final step is to take the square root of both sides.
