--------
hypotenuse = 12
each side = "x"
-----
Use Pythagoras to solve for "x":
x^2 + x^2 = 12^2
------
2x^2 = 144
x^2 = 72
x^2 = 36*2
----
x = 6sqrt(2) (each side is 6sqrt(2)

If it's a 45 45 90 triangle, it has some special formulas for sides
It is a right triangle but also isosceles triangle where you have two sides equal each other.
those two sides will be x, and then the hypotenuse will be
Now you have the hypotenuse which means you have =
=
=
TA-DAH
Your two other sides are :D
