It can be any length; a right angle triangle just needs to include a right angle somewhere. But length has nothing to do with whether it is a right angle or not.

'A' squared, plus 'B' squared, must equal 'C' squared, but only if the 'C' side is the hypotenuse (long side). A right (or left) triangle MUST have ONE 90-degree angle.
with the three sides you know it will be a triangle, it is a right triangle, it is not an equilateral triangle or an isosceles triangle... so it must be a right scalene triangle

The hypotenuse of an isosceles right triangle is 13 centimeters long. How long are its sides?
