Answer:
No, they do not make a right triangle.
Step-by-step explanation:
Use the Pythagorean Theorem to see if the sides form a right triangle.
[tex]a^2+b^2=c^2[/tex]
'20' will be 'c'. It is the largest number in the sides given.
'8' will be 'a' and 17 will be 'b'.
[tex]8^2+17^2=20^2\\\rightarrow 8^2=64\\\rightarrow 17^2 = 289\\\rightarrow 20^2=400\\64+289=400\\\boxed{353\neq 400}[/tex]
The sides do not make a right triangle. They do not satisfy the theorem.
