3 of anything positive is greater than 2 of the same thing.
I can't think of an exception.
Here you go :) AA (Angle-Angle) If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.
This is quite easy, but anyway:
In order, they are
3, 4, 4, 5, 5, 5, 5, 7, 7
7 - 3 = 4
4 would be the range
Change x+y=5 to y=5-x
x+5-x=-3
0=-8
The answer is no solution. :)
