❶It is calculated this way: The hypothenuse is the longest side of the triangle and is opposite of the legs.

## Sure ... ?

This theorem is a squared plus b squared equals c squared where c is the hypotenuse, and a and b are the legs. The formal definition states "the square of the hypotenuse is equal to the sum of the squares of the other two sides.

A and B represent the two legs of the right triangle and C represents the hypotenuse, or the longest of the three sides. This therom is also known as the Pythagorean Theorem. A and B represent the two sides while c stands for the hypotenuse. Pythagoras theorem is used in right angle triangle only.. Pythagoras was an ancient Greek mathematician. This theorem is called the Pythagorean theorem.

The Pythagorean theorem describes the relationship between the three sides of a right triangle. He found the relationship to be: Read as A squared plus B squared equals C squared. This theorem applies to triangles. C would represent the hypotenuse or the longest side of the triangle. A and B would be the other two sides. This theorem only works on right triangles i. What is the theorem of Pythagoras. Expert Answers durbanville Certified Educator.

Related Questions How do you calculate surds? And what does it have to do with Pythagoras theorem? The hypotenuse squared is Given below is the derivation of the Pythagoras Theorem: Take note that the Pythagorean theorem can only be applied to right triangle. This formula is used when one of the missing sides are to be calculated. This image has been Flagged as inappropriate Click to unflag. Image 1 of 1. The formula is written as: The theorem, as stated by previous answers, is: The Pythagorean Theorem is: One side that is not the hypotenuse [A and B can be either side] B: One side that is not the hypotenuse [A and B can be either side] C: The last side is the hypotenuse [The side that is longer].

The pythagorean theorem is: The Pythagorean theorem is The Pythagorean theorem is used to find the side lengths of a right triangle.

Side AB is common for both triangles. So, we can write:. For example, take 3, 4, 5. There are many such sets of integers like this: People have been using these triples even before human beings learned to write.

The Theorem The square of the hypotenuse of a right angled triangle is equal to the sum of squares of other two sides. See the attached snap of the triangle below Click on it to enlarge: So, as per Pythagoras theorem we can write that: Practice Problems Solve the following examples. Assume c is the hypotenuse of a right angled triangle and a, b are the other two sides of the same triangle: The simplest proof of the theorem is based on the similar triangles concept: Drop a line from A to D which is perpendicular to BC.

So, we can write: Real Life Examples Making a perfect rectangular basketball and volleyball court.
