Proof: Sides of Rhombus Congruent 4
Let's prove the following theorem:
if WXYZ is a rhombus, then distance XY = distance YZ
Proof:
Given
| 1 | WXYZ is a rhombus |
|---|
| # | Claim | Reason |
|---|---|---|
| 1 | distance WX = distance XY | if WXYZ is a rhombus, then distance WX = distance XY |
| 2 | WXYZ is a parallelogram | if WXYZ is a rhombus, then WXYZ is a parallelogram |
| 3 | distance WX = distance ZY | if WXYZ is a parallelogram, then distance WX = distance ZY |
| 4 | distance XY = distance ZY | if distance WX = distance XY and distance WX = distance ZY, then distance XY = distance ZY |
| 5 | distance XY = distance YZ | if distance XY = distance ZY, then distance XY = distance YZ |
