Proof: Sides of Rhombus Congruent

Let's prove the following theorem:

Proof:

Proof Table

#	Claim	Reason
1	distance WX = distance XY	if WXYZ is a rhombus, then distance WX = distance XY (Rhombus Property)
2	WXYZ is a parallelogram	if WXYZ is a rhombus, then WXYZ is a parallelogram (Rhombus Property)
3	distance WX = distance ZY	if WXYZ is a parallelogram, then distance WX = distance ZY (If Parallelogram Then Sides Congruent B2)
4	distance XY = distance ZY	if distance WX = distance XY and distance WX = distance ZY, then distance XY = distance ZY (Transitive Property of Equality Variation 2)
5	distance WZ = distance XY	if WXYZ is a parallelogram, then distance WZ = distance XY (If Parallelogram Then Sides Congruent)
6	distance WZ = distance ZY	if distance WZ = distance XY and distance XY = distance ZY, then distance WZ = distance ZY (Transitive Property of Equality)
