Created by Sal Khan and Monterey Institute for Technology and Education. Posted 11 years ago. Given a right triangle, which is a triangle in which one of the angles is 90, the Pythagorean theorem states that the area of the square formed by the longest side of the right triangle (the hypotenuse) is equal to the sum of the area of the squares formed by the other two sides of the right triangle: In other words, given that the longest side c = the hypotenuse, and a and b = the other sides of the triangle: This is known as the Pythagorean equation, named after the ancient Greek thinker Pythagoras. Loe can paint 27 feet of fence in 4.5 hours. How did you know right off that they are asking for the principal square root? Find the third side in simplest radical form: The ratio of potatoes to turnips is 1:1 if there are 476 potatoes now turnips are there? Math Geometry Find the length of side x in simplest radical form with a rational denominator. Dividing by a radical? And with a 30-60-90, the measure of the hypotenuse is two times that of the leg opposite the 30 angle, and the measure of the other leg is sqrt(3) times that of the leg opposite the 30 also seen in the diagram below. In fact, rules of multiplication and the properties of radicals give a b c d = (a c) (b d), where k = lcm(n,m) (the least common multiple, see the LCM calculator), s = k / n, and t = k / m. The formula may seem scary, but, in fact, it's really simple in most cases (e.g., when n = m). Well, one of the greatest assets to knowing the special right triangle ratios is that it provides us with an alternative to our calculations when finding missing side lengths of a right triangle. It follows that the length of a and b can also be determined if the lengths of the other two sides are known using the following relationships: The law of cosines is a generalization of the Pythagorean theorem that can be used to determine the length of any side of a triangle if the lengths and angles of the other two sides of the triangle are known.
