Answer:
A. 6, 8 and 10
Step-by-step explanation:
To form a right triangle, side lengths must satisfy the Pythagorean Theorem
a² + b² = c². Substitute the side lengths into the formula. Remember, a is the shortest side and c is the longest side.
6² + 8² = 10²
36+64 = 100
100 = 100 works
3² + 5² = 6²
9+25 = 36
34 = 36 does not work
7² + 8² = 10²
49 + 64 = 100
113 = 100 does not work
14² + 20² = 25²
169 + 400 = 625
569 = 625 does not work
