a When we name congruent polygons, we must list corresponding vertices in the same order. Therefore, in order to identify the congruent parts, we need to look at the order of the vertices in the congruence statement.
△ B A N D ≅ △ L U C K
The first vertex on the left is congruent to the first vertex on the right, the second vertex on the left is congruent to the second vertex on the right, and so on. Therefore, we can conclude that ∠ U≅ ∠ A.
b As in Part A, using the order of the vertices, we can say that D B ≅ K L.
c Just as we did in the previous parts, we can use the order of the vertices to say that N D B A ≅ C K L U.
