if the triangle has one right angle in it
If it has no right angles, it is not a right triangle and therefore you cannot name a hypotenuse of that triangle. Which implies you cannot find that side's measure.
It is the longest side of a right angle triangle.
If a triangle is an isosceles triangle as well as being a right-angled triangle, the size of the two angles (that are not right angles) are 45 degrees.
By using Pythagoras' theorem for a right angle triangle.

It has a 90 degree angle..
how to find the perimeter of a right angled triangle using the area
It is the longest side of a right angle triangle.
If a triangle is an isosceles triangle as well as being a right-angled triangle, the size of the two angles (that are not right angles) are 45 degrees.
The 90 degree angle in a right angle triangle is opposite its hypotenuse.
By using Pythagoras' theorem for a right angle triangle.
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.
Use the information about the right triangle that you're given, together with all of the things you've learned that are true about every right triangle.
it must be a right triangle.
