Your body's endocrine system secretes and controls the hormones that regulate many body processes including metabolism, use of nutrients, excretion, and reproduction. 1  As you age, these systems become less efficient, leading to changes in our bodies, such as menopause.
The Pythagorean (puh thag or ee un) Theorem, also called the Pythagorean Property, says that the sum of the squares of the lengths of the legs of any right triangle is equal to the square of the length of the hypotenuse,
The Pythagorean Theorem has many proofs. One of the most famous was that of Euclid, the Greek mathematician who was born around 300 B.C. Pythagoras also developed a method of tuning instruments called the Pythagorean tuning. If Pythagoras committed any of his theorems or thoughts to paper, no one has yet found them, though there were forgeries.
