Answer 2

hah, i dont care about medals ,

Answer 3

The dilation means all the distances from the center of dilation will be changed by the dilation factor...

Here the center is on a vertex of that triangle

Answer 4

The sides only go in X or Y directions here, the bottom A(-2,2) to B(-8,2) is 6 units long

AB = 6

The corresponding point on the dilated triangle will be 1/3 of that, or 2 long

Answer 5

So point E will be 2 away from point A... E(-4 , 2)

Answer 6

Point A is the center and stays where it is, and the other top point changes the same as the first one...
