Answer:

No

Explanation:

We can check this using the Pythagorean Theorem,
a^(2) + b^(2) = c^(2) .

First, we can plug our two smaller sides in for a and b, and the largest side in for c.,

5^(2) + 20^(2) = 25^(2)

Next, we can check the left side of the equation, which we find to be:

$5^(2) = 25\\20^(2) = 400\\$

Then, we can add these products and achieve the result of 425

Finally, we can solve the right side of the equation, which equals 625

As 425 ≠ 625, this equation fails the Pythagorean Theorem, and is therefor false.
