Which of the relations given by the following sets of ordered pairs is a function? A. {(1,2),(2,3),(3,4),(2,1),(1,0)}
B. {(2,−8),(6,4),(−3,9),(2,0),(−5,3)}
C. {(1,−3),(1,−1),(1,1),(1,3),(1,5)}
D. {(−2,5),(7,5),(−4,0),(3,1),(0,−6)}

ΔADC ≅ ΔEBC

Step-by-step explanation:

For two Triangles to be congruent by ASA, they have to have two angles which are the same, and their included sides must also be equal(the side between the two angles).

For this scenario:

Thus,

Both triangles have two angles of the exact same size, with a side length between the two angle of the exact same size.
