Does 4.5, 6, 7.5 form a right triangle

If these sides formed a right triangle, then a^2 + b^2 = c^2 would be true

a & b are the two legs

c is the hypotenuse (longest side)

a = 4.5

b = 6

c = 7.5

Plug those values into the pythaogrean theorem and let's see if we get a true equation or not

a^2 + b^2 = c^2

4.5^2 + 6^2 = 7.5^2

20.25 + 36 = 56.25

56.25 = 56.25 ... true equation

Since we get a true equation, this means the original equation is true for the given a, b, c values. So we do have a right triangle.
