Which of the following reasons will complete the proof?

sas
asa
sss

The answer is ASA

Step-by-step explanation:

In order to determine the correct reason, we have to know which angles and sides are the same.

According to the attached image:

we know that side AD has the same length that side BC.we know that angles 2 and 4 are the same. The same situation for angles 1 and 2. The reason is if lines are parallel, then alternate interior angles are the same.ΔADM has the order: ∠2 -side AD-∠1ΔBCM has the order: ∠4 -side BC-∠3

Therefore, if ∠2=∠4; AD=BC; ∠1=∠3, the proof that the triangles are congruent is ASA.

4in2 is the answer

Step-by-step explanation:

each square is 1 * 1, so 3 squares = 3 the triangles are 1 * 1  divide by 2 which = 1/2 * 2 triangles =1 so the answer is 4 , I passed on the test
