Adam draws three parallelograms. he measures the sides of each figure, as shown.

what is a reasonable conjecture for adam to make by recognizing a pattern and using inductive reasoning?

in a parallelogram, all sides are congruent.

in a parallelogram, opposite sides bisect each other.

in a parallelogram, opposite sides are congruent.

in a parallelogram, all sides bisect each other.

In a parallelogram, opposite sides are congruent.

Step-by-step explanation:

Writing the lengths of the sides of the parallelograms shows him a pattern for the side lengths of opposite sides.  Doing this will show him that opposite sides are congruent.

x=4

y=7

Step-by-step explanation:

x=4 because the left and right sides are equal

the upper side should equal the bottom side

so y+5=12

y=12-5

y=7
