It is the same as I proposed earlier................if a triangle...........had a hyp of 1....................a right triangle...............what could its other two sides be??  The only exact way of doing it is making one side the square root of two and the other of i................the imaginary unit............

The bottom side is 1/2........................or 0.5 in decimal from.........per the P theorem.............0.5 squared is 0.25....................................so what is the length of the side along the Y axis....................it it is like................(0.5) squared..............+ b squared...............= 1 squared..........................b is the side along the Y axis...............................1/2 squared is 1/4.............or 0.25.........................per algebra............subtract that from one...................1 - 0.25 = 0.75..................so B squared = 0.75................the square root of 3/4 is .866025.........per MS Excel.......................

0.5
0.5		0.75
0.25		0.866025
