Answer:
Parallelogram, I think
Explanation:
I thought it was a rectangle because there were 2 sets of parallel sides with one set being a greater value than the other. What threw me off was the 45 degree angle. A rectangle's 4 angles are all 90 degrees. The only quadrilateral I knew that had 2 sets of parallel sides, has one side length greater than the other and did NOT have all 90 degree angles was the parallelogram.
hope this helps!
