Answer:
B
Step-by-step explanation:
A proportional relationship is a relationship which crosses through the origin (0,0) and which has a proportional constant. We can determine this either by finding (0,0) where x=0 and y=0 in the table or by dividing y/x. None of the tables contain (0,0) so we will divide y by x. We are looking for a table which when each y is divided by its x we have the same constant appearing.
<u>Table A</u>

These fractions are not equal. This is not proportional.
<u>Table B</u>

These fractions are equal and each shows the numerator to be half of the denominator. This is proportional.
<u>Table C</u>

These fractions are not equal. This is not proportional.
<u>Table D</u>

These fractions are not equal. This is not proportional.
The opposite sides are equal in length.
Step-by-step explanation:
Opposite sides of a parallelogram must be congruent. This is a property of all parralelograms.
Answer:
B
Step-by-step explanation:
