Does a = 8 b=15 c=17 make a right triangle and why

Ok so pythagorean theorem is
a^2+b^2=c^2
plug it in
8^2+15^2=17^2
64+225=289
289=289

yass it works so that means they do make a right triangle

yes, they make a right triangle because they're a pythagorean triple and pythagorean theorem works when you plug the numbers in.

Maybe fx = lxl because of the way the x is positioned is that what he
