Answer 2

These are 2 right triangles with:
1: A common side (AD)
2: Equal length hypotenuses (BC and EC)
3: An equal angle (AB and DE are supplementary to the same line AD)

Answer 3

This doesn't make sense. A line cannot be supplementary to another line--only angles can be supplementary to each other.

Otherwise, you would use a theorem that is discussed in your book to help you figure out how the triangles can be congruent to each other.

Answer 4

Supplementary is not a term that can refer to lines. You must have a third letter which would make these angles.
