* I didn't understand the points of questions 4 and 5, but I made answers based on my own interpretations:

1. Which of the following pairs of sides are congruent? (c. AR and BE)
Congruence between line segments requires that they be of an equal length. Lines AR and BE fit this definition, as opposite sides in parallelograms are always congruent.
2. Find x, if line BA were 2x units long and line ER were 100 units long. (b. 50)
As we said, lines AR and BE are congruent, meaning equal in length. Thus, 2x must be equal to 100.
After the division of both sides of this equation by 2, we find:
