Missing lengths of a 45°-45°-90° Special Right Triangle given Hypotenuse length = 18

Leg lengths of a 45°-45°-90° Special Right Triangle are equal
Leg lengths =
Hypotenuse length/√2

Leg lengths =
18/√2

Rationalize to remove the radical from the denominator:
Leg lengths =
18 * √2/√2 * √2

Leg lengths =
18√2/2

Leg lengths = 9√2 = 12.727922061358
