Pythagorean theorem will be applied to right triangles. The formula is a^2+b^2=c^2 where a and b represent the legs of the truss de c is the hypotenuse. Now let’s say I had a leg that was 4 inches and a second leg that was 8 inches. I would then have to try and find the hypotenuse. So plug it into the equation
4^2+8^2=c^2
Now 4 to the power of 2 is 16 and 8 is 64
16+64=c (note we got ride of the ^2 for the c)
So 80=c
Now what we want to do is take the square root of 80 since our c needs to be rooted. So the square root of 80 would be your answer.
