If you are given the hypotenuse and the base then use 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.

It is the longest side of a right angle triangle.

The sine of an angle in a right triangle is opposite/hypotenuse, where opposite is the only side that is not adjacent to the angle you want to find the sine of, and the hypotenuse is the side opposite the right angle in the triangle. Just find opposite/hypotenuse.

No dimensions have been given but to find the hypotenuse of a right angle triangle use Pythagoras' theorem.

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.

If it's a right angle triangle then use Pythagoras' theorem to find the 3rd 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.

By definition, the hypotenuse is the side opposite the right angle in a right angled triangle. Therefore, a hypotenuse does not exist as one of the three sides in a non-right angled triangle.

The sine of an angle in a right triangle is opposite/hypotenuse, where opposite is the only side that is not adjacent to the angle you want to find the sine of, and the hypotenuse is the side opposite the right angle in the triangle. Just find opposite/hypotenuse.
