Final Answer:
1. Yes, because both pairs of opposite sides are equal and parallel (AB = CD = 9, AD = BC = 11).
2. Yes, because both pairs of opposite sides are equal and parallel (EF = GH = 4.2, FG = HE = 13).
3. EF = 7, FG = 5, GH = 7, HE = 5
4. Perimeter = 24
5. EF = 8, FG = 6
6. Figure EFGH is a parallelogram because opposite sides are equal and parallel (EF = GH = 7, FG = HE = 5) and the slopes confirm parallelism: slope of EF = slope of GH = 2/3, slope of FG = slope of HE = −1/2.
7. Slopes: AB = −1, BC = 0, CD = −1, DA = 0 → AB ∥ CD and BC ∥ DA ⇒ parallelogram.
8. Lengths: PQ = 5, QR = 4, RS = 5, SP = 4
