Answer:
c²=a²+b²
Step-by-step explanation:
It states that the area of the square built on the hypotenuse's side (c) of a right triangle is equal to the sum of the two areas of the two squares built on the remaining two sides of the triangle (a and b).
So, because they are squares, area of a square is side×side=side², so c²=a²+b²
