The correct statement is:

The longest side of a right triangle is opposite to the right angle.

This is a basic property of right triangles. The longest side, called the hypotenuse, is always opposite the right angle (90°).

Let's break down why the other statements are incorrect:

1. a+b=c² can be used to find a missing side length of a right triangle: This is incorrect. The correct form of the Pythagorean Theorem is a² + b² = c², where a and b are the legs of the right triangle, and c is the hypotenuse.

2. A plus b is equal to c squared can be used to find a missing side length of a right triangle: Again, this is incorrect. The correct equation is a² + b² = c², not a + b = c².

3. Pythagorean Theorem can be applied to any triangle: This is incorrect. The Pythagorean Theorem only applies to right triangles (triangles with a 90° angle).

4. The hypotenuse is the shortest side of a triangle: This is incorrect. The hypotenuse is the longest side of a right triangle, not the shortest.
