## samalami 3 years ago The lengths of the sides of a triangle are given. Classify each triangle as acute, obtuse, or right. 7. 7, 8, 9 (1 point)acute obtuse right 8. 15, 36, 39 (1 point)acute obtuse right 9. 10, 12, 16 (1 point)acute obtuse right xoxox any help is appreciated!!

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

2. ParthKohli

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.
