The pythagorean theorem isn t just an intriguing mathematical exercise. It is named after the greek philosopher and mathematician pythagoras who lived around 500 bce. Anyone who can recall math classes will remember the first lessons of plane geometry that usually start with the pythagorean theorem about right angled triangles. Like the homemade water level sometimes the simplest tools are the best and most accurate.

Remember that a right triangle has a 90 angle which we usually mark with a small square in the corner. It is named after the greek philosopher and mathematician pythagoras who lived around 500 bc. This simple math equation is a carpenter s tool used to find or verify the squareness of a room or object. Pythagorean theorem the well known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse the side opposite the right angle or in familiar algebraic notation a 2 b 2 c 2 although the theorem has long been associated with greek mathematician philosopher pythagoras c.

Remember that a right triangle has a angle marked with a small square in the corner. 3 2 9 plus 4 2 16 is equal to 5 2 25. As allen explains one of the classic uses of the pythagorean theorem is in laying the foundations of buildings. Before we state the pythagorean theorem we need to introduce some terms for the sides of a triangle.

It s utilized in a wide range of fields from construction and manufacturing to navigation. Use the pythagorean theorem. 570 500 490 bce it is actually far older. The pythagorean theorem is a special property of right triangles that has been used since ancient times.

The formulas below can be used to square a wall or deck frame the pythagorean theorem calculate the area of a circle calculate the volume of a cylinder calculate the circumference of a circle and more. In spite of its name the pythagorean theorem was not discovered by pythagoras. Because the 3 4 5 method is simply a modified version of the classic pythagorean theorem. No it s not necessary to be a math major to use this rule.

The carpentry math used for most projects can be narrowed down to some basic formulas and computations provided right here on this page.
