    actually @nicolebears there are some right triangles that you will see that don't have the square in the corner

    and if you add 25, 27, and 48 they don't equal 90

    you would have to use the Law of Cosine because you are given all 3 lengths

    those are the side lengths though and you don't just add them up to get 90 degrees
