Week six concept check What is the Pythagorean Theorem? How is it used? Given a right triangle (a triangle with a right (or 90 degree) angle), The square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the two other sides. The normal way of seeing this is... A^2 + B^2 = C^2. A triangle with sides of length 3ft, 4ft and 5ft is a right triangle because 3^2 + 4^2 = 5^2 (9 + 16 = 25) It is used in a great many ways. You can measure the sides, and prove a triangle is a right triangle, or you

Unformatted text preview: can use the fact that a triangle is a right triangle to calculate one of the sides. One example is in construction. Measure 3 feet from the corner of a deck along one side, and make a mark. Measure 4 feet from the same corner, along the other side, and make a mark. If the two marks are exactly 5 feet apart, your deck has a right angle corner. If you are laying the deck out, you can use this to verify that it is square....
