WebYou can ONLY use the Pythagorean Theorem when dealing with a right triangle. https://en.wikipedia.org/wiki/Square_number. close towards the end how did you solve the square root? At least the worries are in how the equation can be solved. And we deserve a drumroll now. on Introduction, You mistake in the Pythaborean triples : You say there are four basic sets; that is not true there are an infinite set.Secondly, you mention 3,4,5 (which is correct) followed by 6,8,10 which is no basic set (because all numbers are just the same multiple of 3,4,5).A set could be 7,24,25 (you could take it as the third set).There is a wiki about "formulas for generating pythgorean triples". Thus, we obtained two values for the given which is . The third side in the example given would ONLY = 15 if the angle between the two sides was 90 degrees. tells us that A squared-- so the length of one of the Since a squared plus b squared equals c squared, that is the same as c equals the square root of a squared plus b squared. How do you do A squared plus B squared equals C squared? make sure you have your hypotenuse straight. And let's say that they tell us Now the next step is finding B2 the way you do that is to take both your known leg and the hypotenuse and subtract in our case we go B = 144 - 36 therefore B = 108.review- In this method we have to remember that we are trying to find a leg not the hypotenuse.
