Answer:

1. yes

2, no

4. yes

Step-by-step explanation:

1. yes

If both sets of opposite sides are congruent, the quadrilateral is a parallelogram.

2. no

We know two side lengths. We know nothing about the other 2 sides and also nothing about all 4 angles.

The missing angle must be 102°. With both pairs of opposite angles congruent, it must be a parallelogram.
