No it s not necessary to be a math major to use this rule.

Math builders pythagorean theorem garage doors.

This theorem has been used around the world since ancient times. It is named after the greek philosopher and mathematician pythagoras who lived around 500 bce. Like the homemade water level sometimes the simplest tools are the best and most accurate. 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.

The pythagorean theorem is the basis for the 3 4 5 rule. This simple math equation is a carpenter s tool used to find or verify the squareness of a room or object. 3 2 9 plus 4 2 16 is equal to 5 2 25. 570 500 490 bce it is actually far older.

Remember that a right triangle has a 90 angle which we usually mark with a small square in the corner. Before we state the pythagorean theorem we need to introduce some terms for the sides of a triangle. In spite of its name the pythagorean theorem was not discovered by pythagoras. Like thales pythagoras is rather known for mathematics than for philosophy.

The carpentry math used for most projects can be narrowed down to some basic formulas and computations provided right here on this page. Because the 3 4 5 method is simply a modified version of the classic pythagorean theorem. If we plug the following values into the theorem a 3 b 4 c 5 we find that the equation is true. Use the pythagorean theorem.

It s utilized in a wide range of fields from construction and manufacturing to navigation. 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. Remember that a right triangle has a angle marked with a small square in the corner. 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.

As allen explains one of the classic uses of the pythagorean theorem is in laying the foundations of buildings.
