Answer:

when we get the length of these sides we see that each two sides that are in front of each other are equal.

Explanation:

that means it could be either rectangle or parallelogram. (with that said when we draw a perpendicular from one side to the other we see that we need a extra line meaning that none of our sides are perpendicular to each other) that leaves only parallelogram.
