Tips for Solving Pythagorean Theorem Word Problems - When it comes to solving a triangle, there are a number of formulae and theorems that we bring into use. A theorem that helps us find a missing side of a triangle; Pythagorean theorem, also known as Pythagoras' theorem. The theorem provides a fundamental relationship between the base, height, and hypotenuse of a triangle. It is given by the equation; (Hypotenuse)2 = (Base)2 + (Height)2 The hypotenuse is always the longest side of the triangle. After reading the problem, always start by creating a diagram. Always try to identify the sides of a triangle before applying the theorem. The theorem only applies to right-angled triangles. You can make the missing side the subject of the equation to make the solution simple. Memorizing the squares of numbers can help in reducing the overall time one takes to solve the problem. To check if you are going in the right direction, compare the calculated value of hypotenuse, it should always be greater than base and height. These worksheets will help students learn how to solve word problems where they can utilize the use of the pythagorean theorem.

Where Will You Come Across Pythagorean Theorem Word Problems Like This in Real Life?
Understanding right triangle geometry is much more impacting than you could ever imagine. This theorem has some many different applications that it is not even funny. As long as you can establish a single right angle, you can model a diagram that you can better understand with this in mind. When you are given two straight lines that meet at a right angle, you have a great deal of power. Almost all building and home construction is built off of this theorem. This ensures that structures are level and square. This starts when they begin to pour the foundation all the way until they are putting the last piece of sheetrock up. I have taken part in building three decks in my life. If I only had a nickel for each of the times, I referred back to using the Pythagorean theorem to determine if something was level of connecting! I would have a lot of nickels. This concept also extents itself to navigation of all types when we are dealing with vehicles travelling in fixed directions, we can determine how long it will take them to travel. This bring us to the old problem of two trains that start at the same point and go in different directions we then need to calculate how far apart those trains are.
