Option C:

The measure of DF is 5.

Solution:

Given $\triangle A B C \cong \triangle E D F$ .

The coordinates of $\triangle A B C$ are A(0, 2), B(2, 4) and C(2, –1).

To find the measure of DF:

By corresponding parts of congruence triangles are congruent,

BC = DF

Let us find the measure of BC using the distance formula.

x_1=2, y_1=4, x_2=2, y_2=-1

Distance of BC = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$=\sqrt{(2-2)^2+(-1-4)^2}$

$=\sqrt{0+25}$

Distance of BC = 5 units

Distance of BC = Distance of DF

Distance of DF = 5 units

Option C is the correct answer.

The measure of DF is 5.
