The diagonals of a quadrilateralbasicly I have all the lengths of a quad and I need to find the diagonal. Batman shows Superman his new phone. Batman"Alfred, whats the temperature in London?" Alfred"Just a second, sir." Alfred turns on his iPhone."Siri, whats the temperature in London?" Siri  "Six centigrade." Alfred"Six centigrade sir." Batman"See?" #2 20140116 14:02:46
Re: The diagonals of a quadrilateralHi thedarktiger; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20140116 15:37:22
Re: The diagonals of a quadrilateralnah thats the exact problem Batman shows Superman his new phone. Batman"Alfred, whats the temperature in London?" Alfred"Just a second, sir."

Re: The diagonals of a quadrilaterala math book AOPS geometry I am really bad at geometry Batman shows Superman his new phone. Batman"Alfred, whats the temperature in London?"

Re: The diagonals of a quadrilateralThere is no way to answer that precisely, there simply is not enough information. Those distances are all magnitudes without any indication of direction. There was an assumption made by the textbook that was either missed by you or missed by them in editing. The distance can take on many values if you are not given any angles or direction. Again, these are magnitudes and not vectors. For any given assumption, you will get a different distance. If they all lie on a straight line the distance could be either 50 or 350 miles, depending on whether Yourtown lies beyond or before Littlevillage by 150 miles. If we try to assemble a quadrilateral, again, without the angles of sides in relation to each other it can take many forms. So you would be looking for a range of possible values and not a specific magnitude. #8 20140121 22:45:18
