The hypotenuese is the side opposite of the right angle in a right triangle. It's the longest side. To find it's length you add together the squares of the other two sides. Then you take the square root of that. So if the triangle has two sides that are 3 and 4 and is missing the longest side, you do 3^2 + 4^2 = 9 + 16 = 25 then take the square root which is 5. The hypotenuse is 5. Only some triangles will come out with whole number answers.

Only a right triangle has a hypotenuse. An isosceles triangle can be a right triangle but it doesn't have to be. If it's not, then it doesn't have a hypotenuse.
The hypotenuse of a triangle with legs of 35 and 68 is: 76.48
The circumcenter is always on the midpoint of the hypotenuse when it is in a right triangle.
The hypotenuse of right triangle of 300Cm and 400Cm is: 500 cm
