How do you prove the parallegram theorem

Step 1: Prove that both pairs of opposite sides are parallel.

Step 2: Prove that both pairs of opposite sides are congruent.

Step 3: Prove that one pair of opposite sides is both congruent and parallel.

Step 4: Prove that the diagonals bisect each other.

Hope this helps.

astronomers is your final answer! : )

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
