Step-by-step explanation:

Given:In quadrilateral WXYZ , and diagonals bisect each other at point A.

To prove: Quadrilateral WXYZ is a parallelogram.

Proof: Reason 1. Diagonals bisect each other (given)

2.WA=YA and XA=ZA by the definition of bisection.

3. m∠YAZ = m∠XAW Vertical Angles theorem.

4. By the SAS criterion for congruence, ΔWAX≅ΔZAY.

5.∠ YWX ≅ ∠WYZ (Corresponding angles of congruent triangles are congruent).

6.. || converse of Alternate Interior Angles Theorem .

7. m∠XAY = m∠ZAW Vertical Angles Theorem and XA=ZA and WA=YA by the definition of bisection.

8.∆XAY ≅ ∆ZAW SAS criterion for congruence.

9.∠XZW ≅ ∠ZXY Corresponding angles of congruent triangles are congruent.

10.|| converse of Alternate Interior Angles Theorem.

11. Quadrilateral WXYZ is a parallelogram by the definition of parallelogram.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
