The sine of an angle theta that is part of a right triangle, not the right angle, is the opposite side divided by the hypotenuse. As a result, you could determine the hypotenuse by dividing the opposite side by the sine (theta)...
sine (theta) = opposite/hypotenuse
hypotenuse = opposite/sine (theta)
...Except that this won't work when sine (theta) is zero, which it is when theta is a multiple of pi. In this case, of course, the right triangle degrades to a straight line, and the hypotenuse, so to speak, is the same as the adjacent side.
By using trigonometry
By using Pythagoras; theorem for a right angle triangle.
Using Pythagoras' theorem
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.

The hypotenuse of right triangle of 300Cm and 400Cm is: 500 cm
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.
By using Pythagoras' theorem: hypotenuse^2 minus base^2 = altitude^2
It is a right angle triangle and by using Pythagoras' theorem the length of its hypotenuse is 10 feet.
By using trigonometry that is applicable to a right angle triangle.
By using Pythagoras' theorem for a right angle triangle or measuring its longest side
First of all, you have to make sure that it's a RIGHT triangle. That means that one of the angles in the triangle is 90 degrees. If not, then it's not a right triangle, and it doesn't have a hypotenuse. If it IS a right triangle, then the longest side is the hypotenuse.
