How Do You Figure Out The Pythagorean Theorem?

The sum of the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.  An easy way to remember is to call it the 3, 4, 5 rule.  3 squared =9, 4 Squared = 16, add these together (sum of) = 25.  25 = 5 squared, hence the 3, 4 ,5, rule.  This theorem only applies to right angle triangles.

In Pythagorean Theorem, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the sides. The simple formula is c2=a2+b2. If you know the sides of right angel triangle then you can solve the question very easily. For details and examples, visit this website

You take the two smallest sides   also known as A and B, you take those two #s in their spot and square them (times them by them) so if one side was 7 ..... You would do 7x7 and you get 49...... Than you take the other # say it was 3...... 3x3 is 9     add 49+9=58  find the square root of 58 which is 29   and you just found the long side also known as the hypotenuse..... And there you have it!! The pythagorean theorem
