Final answer:
The Pythagorean theorem relates the lengths of the legs of a right triangle to the length of the hypotenuse.
Step-by-step explanation:
The subject of this question is Mathematics.
The Pythagorean theorem relates the lengths of the legs of a right triangle to the length of the hypotenuse. The relationship is given by the equation: a² + b² = c², where a and b are the lengths of the legs and c is the length of the hypotenuse. This equation can be used to calculate the length of the hypotenuse when the lengths of the legs are known.
For example, if the lengths of the legs are 3 units and 4 units, we can use the Pythagorean theorem to find the length of the hypotenuse: c² = 3² + 4² = 9 + 16 = 25. Taking the square root of both sides, we find that the length of the hypotenuse is 5 units.
