Question

Can someone please help me with this one?
Given: ΔABC ≅ ΔFDE

What is the length of DF (DF has a line over it) rounded to the nearest tenth?

5.8
4.2
2.2
3.6

Answer 1

Here is the problem.

Answer 2

do you have the units of triangle abc?

Answer 3

Step 1: this line
Given: ΔABC ≅ ΔFDE

means that triangle ABC is congruent to triangle FDE
that means that line segment AB is the same length as line segment FD
FD is the same as DF (the same length, just going in the opposite direction)

What is the length of DF?
From the above, you know the length of DF is the same as the length of AB

Answer 4

Use the distance formula to find the length of AB
