what is the meaning of the pythagorean theorem
Pythagorean theorem In mathematics, the Pythagorean theorem, also known as Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. The theorem can be written as an equation relating the lengths of the sides a, b and c, often called the "Pythagorean equation":[1]
Mean value theorem This theorem is used to prove statements about a function on an interval starting from local hypotheses about derivatives at points of the interval.
Pi Ï€ is commonly defined as the ratio of a circle's circumference C to its diameter d:[9]
