Answer 4

the only special rules I remember are equilateral (a = b = c) or 30, 60, 90 ( 1: 2: sqrt 3 ratio) or isoceles right angle tri (1: 1: sqrt 2 ratio)... none of the above seem to fit these patterns...

Answer 5

know that the sum of 2 sides is less than (or equal to ) the measure of a third side, then you know that the sides do not make up a triangle.
