the right triangle must have to respect the Pythagoras Theorem
we have the next sides
a=6
b=8
c=10
the square of the sun of minor sides need to be equal to the square of the greater side
in this case
[tex]10^2=6^2+8^2[/tex][tex]10^2=100^{}[/tex][tex]6^2+8^2=36+64=100[/tex]so the equality is true, so we can say YES it is a right triangle
