State what additional information is required in order to know what the triangles are congruent by ASA

The answer to your question is  third choice ∠E ≅ ∠ R

Step-by-step explanation:

From the picture, we know that EF ≅ FR

And that                                       ∠EFG ≅ ∠RFT  (vertical angles)

So, we need to prove that another angle is congruent to prove ASA.

From the choices, the only possibility is the third answer   ∠E ≅ ∠ R.

Now, we have proof that ΔEFG ≅ ΔRFT

step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
