Does 2.1, 7.2, 7.5 form a right triangle?

In any right triangle

if the legs are lenght a and b and the hypotohuse is lengh c then

a²+b²=c²

the longest length is the hypothuse

so c=hypothuse=7.5

2.1 and 7.2 are the legs

2.1²+7.2²=7.5² should be true if it is a right triangle

evalaute

4.41+51.84=56.25

56.26=56.25

true

they do form a right triangle
