The phytagorean theorem states a^2 + b^2 = c^2
And so your answer is C. (UV)^2+(VW)^2=(UW)^2, because 81+144=225
Since they are squares, the length of one sides square is equal to the area. UV, VW, and UW are all sides on a square. If you square them, you get their area, and then if you add the areas it will prove the phytagorean theorem correct.
