Does each set of side lengths form a right triangle?

Answer: Read the explanation
Step-by-step explanation: (27+32)^2 does NOT equal 45^2, which means its not a right triangle.
(9+40)^2 DOES equals 41^2. Therefor making it a right triangle
Answer:
27ft, 32ft, 45ft : Not a Right triangle
9ft, 40ft,41ft: Right triangle
Step-by-step explanation:
45^2 (?) 27^2 + 32^2
2025 (?) 729 + 1024
2025 ≠ 1753; Not a Right triangle
41^2 (?) 9^2 + 40^2
1681 (?) = 81 + 1600
1681 = 1681 ; Right triangle
