The longest side of the triangle is 5! 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 (that means multiplying them by themselves), then add those two numbers together, we will get the square of the longest side. So, 3 squared is 9, and 4 squared is 16. When we add 9 and 16, we get 25. The square root of 25 is 5, which is the length of the longest side!
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, if one side is 3 and the other is 4, we calculate it as follows: c² = a² + b², which means c² = 3² + 4². Therefore, c² = 9 + 16 = 25, and taking the square root gives us c = 5. Thus, the hypotenuse is 5.
