so for the first one it would be a^2+b^2=n^2 then for the next one you can use what’s called a proof by contradiction. That is, you can prove something is true because it cannot be false. for the first one i'm going to do 6^2+3^2=45^2 then for my second one i did 45^2=n^2. and then for the next one you would just have to multiply the number by its self so u got 2025=n^2. and then for d it would be yes because of the proof by contradiction. and for e it shows that the triangles could have similar sides. and f yes because one angle is a right angle.
