Which side lengths form a right triangle?

Answer:
B) 1, 8, √65
Step-by-step explanation:
For 3 side lengths to form a triangle the sum of two random sides must be bigger than the third side and their differences must be smaller than the third side.
1+8 > √65 because √65 is approximately 8.1
8-1 < √65
Answer:
B. 1,8,(65)½
Step-by-step explanation:
For the side lengths to form a right triangle they have to obey the Phythagorean Theorem which when paraphrased says " the square of the longer side is equal to the sum of the squares of the other sides"
A . 2² + 15² = 4 + 225 = 229
17² = 289
Not a Phythagorean triple
B. 1² + 8² = 1 + 64 = 65
(65½)² = 65
A Phythagorean triple
C. 2² + (80½)² = 4 + 80 = 84
9² = 81
Not a Phythagorean triple.
