What is the Pythagorean theorem and how is it used?

The Pythagorean Theorem is a fundamental concept in mathematics that explains the relationship between the sides of a right triangle. It states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

The theorem can be written as follows: c^2 = a^2 + b^2, where c is the hypotenuse and a and b are the other two sides. This theorem can be used to find the length of any side of a right triangle as long as the other two sides are known.

The Pythagorean Theorem has many applications in various fields, such as architecture, engineering, physics, and even astronomy.

For example, architects and builders use the theorem to ensure that buildings are built with accurate right angles. Engineers use the theorem to design bridges and other structures that require precise measurements. Likewise, astronomers use the theorem to calculate distances between celestial bodies.
