Andrew claims that a wooden bookend in the shape of a 45° 45° 90° right triangle has side lengths of 5 in., 5 in., and 8 in. Is he correct? If so, show the work and if not, show why not.
can someone help me?!? i don't get what to do first

Using the Pythagorean Theorem: a^2 + b^2 = c^2
5^2 + 5^2 = 8^2
Is he correct?
