obtuse
right

9. 10, 12, 16 (1 point)acute
obtuse
right

xoxox any help is appreciated!!

Answer 1

Do you know how the system works for all the three triangles?

Answer 2

In acute:

\( \color{Black}{\Rightarrow a^2 + b^2 > c^2}\)

In obtuse:

\( \color{Black}{\Rightarrow a^2 + b^2 < c^2 }\)

In right:

\( \color{Black}{\Rightarrow a^2 + b^2 = c^2 }\)

IMPORTANT NOTE: C IS SUPPOSED TO BE THE LONGEST SIDE LENGTH IN ALL OF THEM.
