Since the definition of a parallelogram literally says that it's a quadrilateral with 2 parallel sides, we have AB || CD so the 2 other sides (AC and BD) need to be either similar or parallel (either works, due to that if they're similar we can prove that since AB || CD that they're parallel). B is our answer
the second one 6,6,6 it is a square all the others seem like a triangle
Hint: if you were to graph this, and it curves, then its a linear, if not its straight, then its non linear
The answer to the questions
