Answer:

2.8

Explanation:

From the congruence statement, we see that AB corresponds with EF; this means they will be congruent.

To find the measure of FE, we will find the distance between points A and B using the distance formula:


d=√((y_2-y_1)^2+(x_2-x_1)^2)

Using our coordinates for A and B, we have


A(0,2)\text{and }B(2, 4)\\\\d=√((4-2)^2+(2-0)^2)=√(2^2+2^2)\\\\=√(4+4)=√(8)=2.828427\approx 2.8
