Answer:
see attached
Explanation:
The table is filled in below.
To compute the square of the length of a sloped side, you need to sum the squares of the rise and the run. For example, the square of the length of 'a' in triangle F is ...
a² = rise² + run² = 1² +2² = 1 +4 = 5

Additional comment
When computing the slopes of the various triangle sides, you need to pay attention to the sign of the "rise" for a positive "run."
For the distance purpose here, the rise and run are squared, so their signs are irrelevant. You can treat them all as positive numbers.
