(0,4) (0,-2) (-2,0)
for the reflection over the x-axis, all the y values go to their opposite (0,-4) (0,2) (2,0)
then at the rotation it goes (-x,-y) and becomes (0,4) (0,-2) (-2,0)

Answer:
2,4 and 7 do not form a triangle
Step-by-step explanation:
To form a triangle, knowing the 3 sides, then
The sum of any 2 sides must be greater than the third side
Consider 2, 4, 7
2 + 4 = 6 < 7
2 + 7 = 9 > 4
4 + 7 = 11 > 2
Since 2 + 4 < 7
Then these 3 sides would not form a triangle
