    remember these ? \[\rm sin \rm \theta = \frac{ opposite }{ hypotenuse }~~~~ \cos \theta = \frac{ adjacent }{ hypotenuse } ~~\tan \theta = \frac{ opposite }{ adjacent }\]

    With the 45:45:90 method, the legs would be the same size, and the hypothenuse would be the same length of the leg multiplied by \[\sqrt{2}\]
