the hypotenuse is always the longest side of a right triangle, and is the side opposite the right angle
there HAS to be a right angle square for there to be a hypotenuse, because if there isnt a square determening the right angle, there is no hypotenuse.
In a right angled triangle, the side opposite the right angle is called the hypotenuse.
Pythagorean Theorem states that in any right-angled triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b).
The sides that are not the hypotenuse are called legs or arms.
If we know the lengths of two sides of a right-angle triangle, then we can use the Pythagorean theorem to find the length of the third side.
