The longest side of the triangle, called the hypotenuse, is 5 units long! We can find this using a special rule called the Pythagorean theorem. It tells us that if we take the lengths of the two shorter sides, which are 3 and 4, and square them (3 times 3 and 4 times 4), then add those two numbers together, we will get the square of the hypotenuse. So, 3 squared is 9, 4 squared is 16, and when we add them, we get 25. The square root of 25 is 5, which is the length of the hypotenuse!
To find the hypotenuse of the right triangle, we can apply the Pythagorean theorem. This theorem states that the square of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b). In this triangle, the lengths of the two sides are 3 and 4. Therefore, we calculate: c² = 3² + 4², which simplifies to c² = 9 + 16, giving us c² = 25. Taking the square root of both sides, we find that the hypotenuse (c) is 5.
