A square pyramid is a pyramid with a square base. In this problem, this base is formed by the points B, C, D and E as illustrated in the Figure above. So, the correct answers are:
First. (BC←→ and DE←→)
This is indicated in Figure 1. As you can see, the red lines are parallel, that is:
![\overline{BC} \ is \ parallel \ to \ \overline{DE}](https://tex.z-dn.net/?f=%5Coverline%7BBC%7D%20%5C%20is%20%5C%20parallel%20%5C%20to%20%5C%20%5Coverline%7BDE%7D)
Recall that two lines are parallel if they are always the same distant apart in which case they are <em>equidistant, </em>that is, they never meet.
Second. (CD←→ and BE←→)
This is indicated in Figure 2. As you can see, the green lines are parallel, that is:
![\overline{CD} \ is \ parallel \ to \ \overline{BE}](https://tex.z-dn.net/?f=%5Coverline%7BCD%7D%20%5C%20is%20%5C%20parallel%20%5C%20to%20%5C%20%5Coverline%7BBE%7D)
